Make a mark for reference on a knife

Almost every knife I sharpen gets logged in my excel sharpening file.  I record: 1.  Which vise I used (I have both setups); 2.  Which of the two key positions I used (high or low); and 3. The distance from the forward face of the vise to the tip of the blade (I make a small Sharpie mark at this distance when I re-sharpen.)  I also record the bevel angle(s) and the grits or film used.

I respharpened a blade this afternoon and missed the distance to tip by 5mm (I was accidentally using the record of a very similar knife).  I used the Sharpie method just to check it and it worked just fine.  This suggests that the fore-and-aft position doesn’t need to be quite so precise, at least for similar knives.

I don’t normally (as in almost never) mount a blade in a non-level position.  By that I mean that I almost always mount the blade with the spine contacting both pins.  When I do go non-level, I’ll also record the horizontal angle of the edge with an angle cube held right on the edge at the heel.  This is made easier by using the DXL 360 angle cube, which has V-notches on all four sides
