I bought my first, and until recently, only straight razor (Thiers Issard Spartacus 7/8) about 5 years ago. It truly gave a great shave right out of the box and has continued to do so, having been maintained with only daily stropping on leather and about once every week or so on the linen side.

In a burst of enthusiasm I recently purchased 2 more razors, a Mastro Livi 8/8 and a Henckels 8/8 Friodur. Neither one came close to the TI so, following Lynn's progression on the DVD he made, I tried the 3/3, 1/3, 1/5 pyramid on a 4000/8000 Norton stone. Didn't seem to improve things much and, truth be told, they might even shave a little worse i.e. drag a little rough and don't cut much whisker. I tried some of the tests for overhoning, but am not sure if I'm interpreting them correctly.

Given the above info, is it possible to make a guess as to over vs. underhoning on these razors?

Thanks.
