Gritomatic Laser Edge Goniometer Master - Knife angle

This is a basic instructional video on how to use the Gritomatic Laser Edge Goniometer Master to measure the edge angle and primary grind on a knife.
NOTE - At around 6:40 I meant to say "Primary Grind", NOT "Primary Edge Grind".

Good Informationen

Wonderful video; Informative! Thank you

[@HellGatefr2]

Thanks for this nice demo, very insightful, now I kinda want to make one

[@donham512]

great vid !!

[@iSharpen]

Very interesting. Even though they're out of stock they're cheaper than I expected. Looks like a fun tool to have even just for curiosity or training purposes. The way my Tormek angle finder wears out I'm never sure how much to trust it. I'm sure it makes very little difference in real life but it's fun to be accurate.

Can this instrument be used for kitchen/chef knives?

[@777edge]

Yes, most definitely! I'm only using small knives for demonstration purposes.

[@Dissentient01]

Wonder what kind of a reflection the laser gives with a full convex grind?

[@777edge]

It's in the video at 6:08

@@777edge Sure looks like it has a secondary bevel but yeah the laser print is different.

[@777edge]

@@Dissentient01 I sharpened that knife specifically to a convex edge on a guided sharpener to show how it displays in the video. There is no secondary / microbevel on that knife. The inside dots (around 3 degrees a side) on the scale is the primary grind of the knife (not the edge bevel). The outside lines is the diffraction of the laser off of the convex edge. I used the wrong words to describe the inner dots in the video, I said "primary edge" but I meant to say "primary knife grind". 🙂

Problem is the magnets will scratch the blade of some knives

[@GlennLaguna]

What do you think about shining the laser in this fashion... czcams.com/video/3ICnxj6TDjs/video.html

[@777edge]

Yeah, it also works but just takes a much more complicated jig setup.
