The Tension Sharpener | DIY Japanese Whetstone Jig

Forget expensive sharpening systems! In this video, I'll show you how to build a professional-grade, adjustable-angle sharpening jig for your Japanese whetstone (or any water/oil stone) using simple hardware store parts.

This DIY "Tension Sharpener" uses a turnbuckle (tal-rep) to create precise, rock-solid control over your knife's angle. It's cheap, incredibly effective, and will give your knives a razor-sharp, consistent edge every time.

In this tutorial, you'll learn:

What parts you need (turnbuckle, threaded rod, knobs, wood scraps).

How to assemble the main adjustment mechanism.

How to calibrate and set your desired sharpening angle.

A quick demo sharpening a kitchen knife to a hair-popping edge.

Why this jig works:
The turnbuckle provides micro-adjustable tension, locking the knife in place without play. This eliminates the guesswork and wobble of freehand sharpening, making it perfect for beginners or pros who want perfect repeatability.

Materials List (with example keywords for search):

Small Turnbuckle (Eye & Eye or Hook & Eye)

Threaded Rod (M6 or 1/4")

Wing Nuts or Plastic Knobs
