partitsiip

Partitsiip is a Finnish term for a hand tool used to pare, trim, or separate material along a line. The tool typically features a small, sharp blade mounted in a handle; blades can be straight or slightly curved and are designed to produce short shavings.

In woodworking and carpentry, partitsiip is commonly used for tasks such as cleaning up joints, trimming along irregular edges, and removing waste in narrow spaces where a larger plane or chisel cannot reach. It is related in use to a paring knife or paring chisel in English, but is generally held and guided with the hand rather than struck with a hammer.

The term covers several blade designs that share the core purpose of shaving material away to arrive at a precise edge or surface. Variants differ in blade width, bevel angle, and whether the blade is fixed or replaceable. In related crafts such as leatherworking or jewelry making, a small hand paring blade can be employed for delicate trimming of soft materials.

Care and maintenance: keep the blade sharp with proper honing, clean after use, and oil to prevent rust. Store with protection for the edge and avoid moisture to maintain longevity.
