Saddlers Round Knife C.S. Osborne No. 70
Saddlers Round Knife by C.S. Osborne for skiving and cutting curves and long straights. It features a razor sharp forged steel blade and hardwood handle. This knife fits well in your hand and makes precise cuts every time. The world's leading 5 inch round knife since 1826.
The knife blade measures 5 inches (12.5 cm) wide and 6.5 cm deep. The smooth hardwood handle measures 10 cm long and 3 cm wide (at the widest point).
A Saddlers Round Knife (also known as a head knife) is a traditional leatherworking tool used primarily for cutting, skiving and trimming heavy leather. Its curved, razor-sharp blade allows for precise, clean, and controlled straight or curved cuts without stretching the material, and it is also used to thin leather edges (skiving) and for corner chopping.
Key uses for a Saddler's Round Knife include:
- Cutting Thick Leather: Ideal for cutting heavy leather, such as 4mm vegetable-tanned, that other knives cannot manage in a single pass.
- Straight and Curved Cuts: The rounded blade facilitates long straight lines, intricate curves, and bending cuts.
- Skiving: Used to thin out leather edges or remove material from the back of leather for cleaner, less bulky folds.
- Corner Chopping/Shaping: Perfect for trimming corners and shaping leather pieces.
- Punching/Cutting Holes: Used for cutting out smaller, round pieces, such as those used for building up leather handles
This versatile leather knife replaces multiple specialised cutting tools with a single, highly effective tool. The handle allows for firm, comfortable downward pressure directly from the palm, enabling precise, controlled cuts. When properly maintained, a high-quality, sharp round knife can last a lifetime
