Until recently all I did when a razor needed a touch-up was 15-20 laps on the Y/G Escher followed by 50 on the Nakayama and strop. After this my razors invariably pass the arm hair test. But not the HHT. Feeling uneasy about this I have been trying the last few months to find a touch-up routine that would invariably lead to an edge that passes the HHT.

Until now no luck. The following works for most razors but not all: 20 laps on the Escher followed by 20-50 on the Tam O' Shanter.. This really suprises me as the TOS is usually thought to be less fine than a Y/G Escher.

So here are my questions

1. why do I get a sharper edge going down the grit ladder?
2. what is your routine that invariably gets you a HHT positive result?

BTW until recently I agreed with those who say that very thin hair is unsuitable for the HHT. Nowadays I feel that if the edge is sharp enough it does not matter what quality hair you use for the HHT.
