To choose a handcrafted pocket knife, start with what you plan to cut. A snack, a string, a fruit, the tape on a package: each use calls for a different size, mechanism, and blade. The steel and handle material come next, once the foundations are set. This guide follows that order. It compares sizes, explains the slip joint, lockback, friction, and St. Pierre, then helps you decide between stainless steel and carbon steel, wood and Micarta, small series and a more unique piece. In the end, you will know which model to look at among the handcrafted pocket knives that I make in Courpière, in the Thiers basin.
Quick answer: five criteria, in this order.
- Actual use: what you'll really cut, and where.
- The format: closed length, weight, pocket size.
- The mechanism: consistent with your habits, locking or not.
- The blade and the steel: depending on the maintenance you agree to provide.
- The handle: grip first, aesthetic second.
Start with actual usage
A pocket knife is primarily used for simple tasks: opening a package, cutting a string, preparing a snack, slicing bread, cheese, a fruit, or sausage, accompanying a picnic. It can also become a gift, a regional form that is collected, an object that is passed down. Each of these situations rearranges the criteria.
For light daily use, portability is key: a knife that weighs down your pocket ends up in a drawer. For snacks and the table, comfortable handling and a blade that slices through bread crust are more important. For a gift, choose a mechanism that is easy to explain and simple to maintain. For a regional model or a collector's piece, the shape, mechanics, and quality of fit take precedence over weight. For outdoor use, stay reasonable: a folding blade can handle cutting, but not heavy lateral stress.
| Use | Recommended size | Relevant mechanism | Priority criterion | Point of attention |
|---|---|---|---|---|
| Light daily use | Compact, discreet in pocket | Flat lock, friction | Weight and bulk | Do not oversize |
| Snack and table | Medium blade, comfortable handle | Locking back lock, slip joint | Grip | Wipe the blade after grease and acid |
| Gift | Versatile size | Simple mechanism easy to use | Ease of maintenance | Know the recipient's habits |
| Regional model | Defined by the original shape | Variable according to the model | Silhouette and shape consistency | Check the actual mechanism on the model's page |
| Collection | Free | The mechanism that interests you | Quality of fit and finish | A showcase piece also deserves to be opened |
| Reasonable exterior | Handle safe in hand | Forced notch, or lock if use justifies it | Ease of maintenance in the field | A folding knife is not a logging tool |
Choosing the right size
The size is judged when closed before it is judged when open. The closed length determines the space it takes in the pocket. The weight determines whether the knife will follow you every day or only on Sundays. The thickness and width of the handle determine the grip: a handle that is too thin tires the hand during prolonged cutting, a handle that is too thick is felt with every step.
The length of the blade depends on its use. A small blade is more than enough for mail, strings, and fruit. A medium blade can cut through a country loaf and slice a sausage without effort. Beyond that, one leaves the realm of the pocket knife for that of an object that is taken out on occasion.
Last point, often forgotten: the opening. Traditional spring or friction mechanisms open with two hands. It is a deliberate gesture, not a constraint. If you want a one-handed opening, a mechanism designed for that will be necessary, which leads to other setups.
Choose the mechanism
The mechanism affects the opening action, the feel in use, and the behavior of the blade. In my workshop, I mainly work on the flat lock, the back lock, friction, and some Piedmont-style assemblies. I occasionally make a liner lock or a pump mechanism, depending on the projects. Here is how to distinguish them.
The flat lock
The back lock is a non-locking spring mechanism, also known elsewhere as a slip joint. A back spring holds the blade in the open position as well as in the closed position. Nothing locks the blade: it is the tension of the spring that keeps it in place. It is the mechanism of many traditional French knives. It is suitable for everyday cutting, provided that no pressure is ever applied toward closing.
The lock back
The assisted opening works on the same spring principle, with a noticeable difference: the movement of the blade meets significant resistance. You can feel the spring working when opening, and the blade holds its position more firmly than with a flat detent. However, it does not lock the blade. No spring mechanism does. The assisted opening is suitable for a snack, at the table, and for everyday use, for those who enjoy a crisp mechanical feel under their fingers.
Friction
The friction knife has no spring. The blade is held by the adjustment of the pivot, set to offer just the right amount of resistance. It is the simplest construction that exists: few parts, little to maintain, a smooth and silent opening. In return, this mechanism requires careful use: the hand helps to hold the blade.
The Piedmontese
The Piedmontese is a type of friction knife whose blade usually extends into a bolster at the heel. When opened, the bolster fits under the thumb or in the palm: the hand holds the blade during cutting. Simple construction, instantly recognizable silhouette, and a direct connection between the movement and the tool. Its limitations are those of friction: no spring, no lock, a deliberate use.
Liner lock and pump
The liner lock locks the blade open thanks to a lateral metal strip that comes to sit behind the heel. The pump mechanism locks the blade with a dedicated spring, which is released by acting on its lever. These two setups keep the blade open as long as they are not unlocked, which never exempts one from consistent use. I make them occasionally, on certain projects: they are not the core of my production.
| Mechanism | Spring | Locking | Sensation and use | Strengths | Limitations |
|---|---|---|---|---|---|
| Flat notch | Yes | No | Two-handed opening, traditional grip | Simplicity, easy maintenance | No pressure towards closing |
| Forced notch | Yes, marked resistance | No | Firm blade passage, steady hold | Clear mechanics, held in position | Does not lock the blade |
| Friction | No | No | Smooth opening, minimal mechanics | Few parts, reduced maintenance | Requires careful use |
| Piedmontese | No | No | Lens under the thumb during cutting | Simple construction, identifiable silhouette | Retention ensured by the hand |
| Liner lock | Spring steel side plate | Yes | Blade held open, release with the finger | Secures the open position | Occasionally done in the workshop |
| Pump | Yes, locking spring | Yes | Release by lever action | Proven mechanical lock | Occasionally done in the workshop |
Is a lock necessary? Not necessarily. A traditional well-adjusted mechanism covers the vast majority of uses of a pocket knife. Locking is justified when the use requires it, not as a principle. To explore each family, go through the switchblade knives, the friction knives and the Flat-ground knives for the technical detail.
Look at the blade before the steel name
Many buyers start by comparing steel references. That's putting the cart before the horse. A blade is first judged by its geometry: its profile, point, usable length, thickness, and grind. A thin, well-ground blade in ordinary steel cuts better than a thick blade in reputed steel. Geometry does the work; steel determines how the blade holds its edge and how it ages.
Then remains a simple choice between two families. Stainless steel resists corrosion better: it forgives a late wipe after cheese or fruit, and requires little daily attention. Carbon steel is generally easy to sharpen and develops a patina with use: the blade takes on a gray tint that tells the story of what it has cut, provided it is wiped and dried after use. Neither family is superior to the other. The right question is: what maintenance are you willing to provide?
Beware of steel rankings. Edge retention depends on the steel, but also on heat treatment, grinding, and sharpening angle. A grade name on a sheet tells you nothing about any of that.
Choosing a handle material
The handle is chosen with the hand as much as with the eye. The concrete criteria: touch, long-term stability, resistance to moisture, required maintenance, weight, the way the material ages, and its pattern.
Wood offers warmth in the hand and a unique pattern; it requires avoiding prolonged baths and benefits from occasional maintenance. Stabilized wood is real wood whose fibers have been impregnated with resin: it gains stability and resistance to moisture while retaining its pattern. Micarta is a composite of layers of fabric or paper impregnated with resin: simple, stable, very tolerant to use. Carbon fiber offers lightness and a technical look. Horn and fossil materials provide substances that are not found anywhere else, with more careful maintenance.
A rare material is not automatically a better choice. The material attracts the eye. The assembly must keep the promise.
Small series, regional model or unique piece
My work is divided between several areas. Mass-produced and small series models: a proven design, reproduced in batches, with a better-controlled price and more predictable availability. Permanent models: designs that I keep in the catalog and adapt over the course of the series. Regional reinterpretations: old French shapes redesigned for today's uses. And the more unique pieces: particular material, more advanced finish, specific detail, longer manufacturing time.
None of these categories is worth less than the others. A small series gives you a tested, repairable knife, at the fair price of its manufacturing time. A singular piece gives you an object that exists in only one copy or almost. The question is not hierarchy: it is what you are looking for.
For certain series models, the heat treatment or sharpening can be entrusted to professional partners. I retain at the workshop the design, fitting, assembly, finishing, and inspection. The other pieces are entirely made in my workshop. The details of the steps are explained on the dedicated page: understand the manufacturing.
Some models to guide your choice
Each model answers a different question. Here are a few, to compare with your criteria.
The Hack N Slash is a back lock folding knife, with a hardened stop and stainless steel spring. It is the model of my regular series: a pocket knife made to be used every day, for both quick snacks and daily use. Its angular shape makes it stand out at first glance. Discover the Hack N Slash.
The Asmo D is a friction knife whose pivot screw allows adjusting the pivot resistance. Minimal mechanics, smooth opening, low maintenance: a consistent choice for those who want the simplicity of a springless knife. See the Asmo D page.
The French regional models — the Bulldog, the Breton, the Rouennais, the Alpine — take up old forms of French cutlery, historically produced in the Thiers basin and elsewhere, and redesign them for current use. The mechanism and materials vary according to the series: each model page specifies what is actually assembled.
Common mistakes before purchase
- Choosing only the steel. The geometry of the blade and the fitting matter more than the grade reference.
- Choose only the wood. A beautiful handle does not make up for a poor grip or mediocre assembly. It reveals them.
- Take too large. The knife that weighs in the pocket stays at home. The one you forget on yourself is used every day.
- Demanding a lock without actually needing to use it. A forced lock or well-adjusted friction covers almost all pocket uses.
- Asking a folding knife to do the work of a fixed tool. A pocket knife is neither a screwdriver nor a crowbar. Lateral force damages the pivot and the blade.
- Neglecting maintenance. A carbon steel without wiping rusts. A pivot never cleaned hardens. Nothing serious, but best to know beforehand.
- Buying a story rather than a knife. The story does not cut. Check the grip, the mechanism, and the maintenance before the legend.
Maintaining your pocket knife
A well-maintained pocket knife is passed down; the steps fit in a few lines. Wipe the blade after use, especially after greasy or acidic foods. Dry the knife if it has become damp. Keep the pivot and the spring clean, with a drop of oil from time to time. Maintain the edge regularly rather than waiting for a dull blade. Store the knife in a dry place. And never in the dishwasher: the heat and detergents mistreat both the handle and the mechanism.
If the mechanism becomes loose or if the blade has suffered, returning to the workshop allows for readjustment. The detailed actions are gathered in the guide for maintaining a folding knife.
