Leather skiving knife

A leather skiving knife is an essential tool in leathercraft, used for thinning and leveling edges and surfaces.

About this subject

The leather skiving knife is a manual tool used by leather craftsmen to reduce the thickness of leather in specific areas. This process, called skiving, is essential for creating folds, joints, and finishing pieces such as wallets, belts, and bags. The blade is typically short and beveled, allowing controlled and precise cutting. Variants include the round-point skiving knife for curves and the straight-point for straight edges. Historically, similar tools were used by saddlers and shoemakers since the Middle Ages, evolving over time. Carbon steel is the most common blade material due to its ease of sharpening and durability. Global brands like Tandy Leather, Osborne, and Regad are well-known. Proper use requires practice and technique, holding the knife at a specific angle relative to the leather. Experienced artisans can achieve thicknesses below 1 mm, crucial for high-quality work. Besides manual skiving, electric skiving machines exist, but the manual knife is still preferred for its control and low cost. Maintenance involves always keeping the blade sharp and lubricated to avoid tearing the leather. Interestingly, the term "skive" comes from Old Norse, related to cutting thinly. In Brazil, the technique is common with vegetable-tanned leather and luxury goods, influenced by European and Asian traditions.

Frequently Asked Questions

What is the difference between a skiving knife and a utility knife?

A skiving knife has a short, beveled blade designed for precise angled cuts, while a utility knife has a straight blade for straight cuts. The skiving knife offers fine control over leather thickness, ideal for thinning edges.

How do you sharpen a leather skiving knife?

Use fine-grit sharpening stones (1000 to 6000 grit) or a strop. Maintain the original blade angle (usually 20 degrees) and make smooth strokes. After sharpening, run the blade on a leather strop with polishing compound to remove burrs.

What type of leather can be skived with this knife?

Medium to thin leathers, such as vegetable-tanned and chrome-tanned leather, are ideal. Very thick or stuffed leathers may require other methods first. The knife works best on firm, uniform leather.
