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.
Is the marking just the double of actual edge angle if the job is held exactly vertical? Say if bevel is 10 degree single side, it would show at 10' marking and marking is actually geometrically 20' (20/360) from the bottom tip of blade and w.r.t. exact vertical line passing through spine of blade. Just curious! Regardless, wonderful job making a tool in simple and effective design.
@@SurinderSingh-mu2oj The markings is for each side of the edge. So, 10 degrees on the left side and 10 degrees on the right side. Each edge side's sharpening angle. If you were to have an inclusive angle, then yes it would be 20 total but that's not how sharpening angle is typically measured. It's typically measured as each individual side of the edge, just like the goniometer measures it.
@@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". 🙂
@@777edge Looks like the Master version can only take a knife up to 51mm in blade height, but I have a lot of chef knives that exceed that. The Pro version can handle them, but it doesn't have the magnet assist.
Wonderful video; Informative! Thank you
thx
Thanks for this nice demo, very insightful, now I kinda want to make one
Excellent. Thank you

great vid !!
Good Informationen
How does this work with scissors?
@@FUBAR956 The same way, but you only read an angle on one side of the bevel. You will also need to disassemble your scissors.
Where do you find these Gritomatic Goniometer laser angle finding tools
From www.gritomatic.com. If they don't have it listed, drop them a message on their "contact us" part of their store.

Wonder what kind of a reflection the laser gives with a full convex grind?
It's in the video at 6:08
@@777edge Sure looks like it has a secondary bevel but yeah the laser print is different.

@@Dissentient01 it does indeed
Can this instrument be used for kitchen/chef knives?
Yes, most definitely! I'm only using small knives for demonstration purposes.

@@LtKwasretaken In all honesty, you don't need the magnets at all. The Pro version gives just as accurate readings as the Master.
Problem is the magnets will scratch the blade of some knives
Price
It's for sale on Gritomatic's website. www.gritomatic.com
Uhm okay this is actually pretty genius LOL
What do you think about shining the laser in this fashion... ua-cam.com/video/3ICnxj6TDjs/v-deo.html
Yeah, it also works but just takes a much more complicated jig setup.
BBB edge lol🙃
I would prefer if he would be the one sharpening those knives, for sure !
