OK now i understand the blunting (thanks Gugi), but i will not be making it a practice

yes i know all the coticules, bbw, Escher's thuringens (real ones) and other natural stones i have tried or own behave differently which is why i mainly just use one of type so i have a better understanding of how the razor will respond on it... and mainly they are the stones i like to shave off of.

i know the OP does not have other tools to experiment with and it can be daunting but in time and after watching some of the honing videos closely he should be OK ... but his best bet is to have it honed for him and then learn on an ugly blade....
