What a swivel knife is
A swivel knife has four main parts:
- The yoke, the saddle or finger rest where your index finger sits
- The barrel, which you hold with your thumb and middle finger
- The bearing, which lets the barrel turn
- The blade, which is replaceable
Because the barrel turns, the blade follows curves as you pull the knife toward you. For how to hold and cut, see swivel knife carving: how to hold and cut clean lines.
Choosing the blade width
- 1/4 in is the most versatile and the usual starting size.
- 3/8 in and 1/2 in suit long, gentle curves.
- Smaller blades are for detail work.
Bigger blades are not better for beginners. Start with 1/4 in and add others as your work needs them.
Blade styles and materials
- Styles: straight, angled, hollow-ground and filigree blades. Hairline blades are used for decorative cuts.
- Materials: carbon or tool steel, stainless steel and ceramic. Ceramic stays sharp longer but can chip. Ceramic blades still need stropping.
Most makers sell interchangeable blades. Check the blade fit across brands before you buy.
Fixed or adjustable, barrel and bearing
Adjustable knives let you set the height of the yoke. Fixed knives are simpler. Either works well.
Barrel diameters vary, so choose one that fits your fingers comfortably. Smooth bearings let the barrel turn easily. Cheap knives can feel gritty or loose.
Prices and brands
Prices range from about $15 to $40 for a budget knife to $100 or more for a premium one. Prices vary, so check current listings.
- Entry level: Tandy Craftool swivel knives are budget-priced and widely available.
- Premium makers include Barry King and Leather Wranglers.
Availability and prices change, so verify the current listing before you buy.
Keeping the blade sharp
Most new blades still need honing and stropping before use. Few arrive truly sharp.
- Strop regularly with a leather strop and jeweler’s rouge or a polishing compound. This is essential for any knife.
- A honing guide or jig helps you set the bevel on the blade.
- Watch for dragging. A dull blade drags and tears. A sharp one glides with little pressure.
Common misconceptions
- An expensive knife won’t fix poor technique or a dull blade.
- Bigger blades aren’t better for beginners. The 1/4 in blade is the usual starting point.
- Ceramic blades don’t stay sharp forever. They still need stropping.
Safety
- Store the knife with a blade cover. The blade cuts even when it isn’t in use. For general workshop habits, see leatherworking safety for beginners.
