Thread: TNT after bevel setting.

Hi guys.

Just trying to get an idea of how many of you (if any) use the thumb nail test after the 1k mark.

I did it tonight but I'm going to keep my results and reasons personal right now so I don't get lit up by the pros for suggesting anything.

I use it on knives all the time. I only use it on a razor the first time I set the bevel, after that I use a magnifying glass or microscope.

I think the thumbnail test is an excellent tool. Since I keep a Zeiss stereomicroscope on my honing table I don't bother with the TNT but is a perfectly viable tool for anyone who does not use magnification.

I have never used the TNT,,, if the edge smoothly shaves arm hair after setting the bevel,,, then I move up the progression.

Yup, it’s quick. If it feels good pick up the loupe, if not do some more laps. You can TNT without wiping off the razor. It is a quick test, once you calibrate it to your thumb, it can take some time to learn.

My thumb is pretty actuate but, I still can’t feel chips…

That went a lot better then I expected. I half expected to be brought up on blasphemy charges.

I rarely ever use magnification and the Thumb Nail Test has proved useful on many occasions. Mainly used after bevel setting if but not always to detect chips before stropping and shaving.

Glad to know I'm not going crazy.

I love how different we all are. It's what keeps SRP interesting.

Now would a TNT detect a wire edge??

I find it really helpful after major edge repair where I bread knifed. Very easy to find the dead spots with the TNT
