Hello!
First, Les, excuse me for the wrong name.
And yes, you are completely right concerning the point that a maker should carry his own work.
Personally, for me there are some exceptions. I like the work of other makers, too and if i do not carry something from another maker or factory from time to time i have no possibility to compare my work with others and maybe find some insufficient qualities. For field testing, i like it not only to test them by myself, but to give knives to hunting friends of mine and especially to women in my family for kitchen use. In my opinion there are not many cutting and ergonomic tests in the knife world which can be harder than the work in the kitchen.
Have a nice christmas time,
Achim
