no previous part Part 1 of Helpful Jigs series Part 2: Two Piece Jig to Make 1" Thick Bent Lamination »

Wanted to share this jig I made, to quickly and accurately square up blades for sharpening. I have been doing alot of that lately and wanted to show the device I fabricated. Took pictures today while I made it…. so here we go.

It takes a toggle clamp and some scrap wood to complete.

It’s based on the idea of making a permenant block to reference your honing aid from. Adding the clamp essentialliy gives you an extra hand, so you can focus on getting the guide tight and square.

The first step is to determine your distance. This is different for every angle, blade thickness, and device
used. You can figure that out.

From a lenght of 1/4”, a cut is made this distance. Glue this cut piece, back to the end of the 1/4” material you cut it from. Then glue a section of 3/4” material, of the same width, to the same 1/4 piece.

This part of the jig then gets attached to the top of another piece of 3/4” material, of the same dimensions. For my jig, this new piece of 3/4” material was held back from the end 1/4” . This was to keep it from touching the brass roller, on the bottom of the Veritas guide.

Now center and attach the toggle clamp. making sure the rubber tip, when closed, lands inside the jig. Take a flat square and clamp it into the jig.

Fasten a small section of material, square to one side but NOT PROUD of the jig end. If it hangs out past, it may touch your sharpening device and push it out of square.

THIS IS IMPORTANT

If you make the top half of your jig square and the area the sharpening device refrences is not parallel to the fence, the setup will be OUT OF SQUARE.

Here it is finished. Pretty cool little device, sure to speed up the process and help eliminate error. Hope it helps someone else out.

The only “secret’ to using hand tools is to use sharp hand tools. This jig will help you to hit the same exact angle everytime.

Thanks for reading
