Looking at getting a new straight edge (left my old one when moving). Right now I am looking at the one from sharpening supplies for 24. Not sure if there were any reviews on it or better suggestions, thanks.
Yes for checking stone flatness, thanks.Straight edge? Like a metal ruler?
What do you use?I notice that it is only accurate to within 0.001". That's about 40μm, the equivalent of about 400 grit (US). Probably ok for knives but I would have thought you would want better accuracy for honing SRs.
I have this one, and it works well for me. I’ve never had any issues with it.Looking at getting a new straight edge (left my old one when moving). Right now I am looking at the one from sharpening supplies for 24. Not sure if there were any reviews on it or better suggestions, thanks.
This is what I do as well.The edge of an Atoma is usually straight enough for me.
I don't use a straight edge. You can only lap as flat as your lapping medium. That is where a good well support diamond plate or polished granite slab with W&D comes in. A marker (Sharpie) pen of pencil is then your friend. Marker pen on black Ark and pencil on synthetic whetstones.What do you use?
Carefully measured by holding it up to the light and eyeballing it.All this is a surprise to me... I just never knew I needed a stone flat within .001 inch..
Who'd a thunk it?
I don't know if that was aimed at me but I'm not saying it has to be within .001" per foot...just that when I've checked stones that passed the grid test they weren't all that flat even to the eyeball test. Straightedge to the light across a few axes is good enough for me. Not like I'm pulling out a feeler gauge or something. I don't even do that with my synths, past the initial lapping. Just lap till it starts to stick, rinse and hone. They don't stay all that flat for long anyway.Carefully measured by holding it up to the light and eyeballing it.
