Tal, take this in the spirit I intend it as it is only my personal opinion and standard.
I think a maker's reputation starts growing when he cuts out that first sheath, and it grows in the direction that he guides it through personal criticism and standards. I have any where from 10 to 15 finished sheaths, at any given time, in a brief case that I haul around to shows, hammer ins, etc. Each of these sheaths did not meet my personal standard for one reason or another. Most of the time it's a question of fit, either too loose or too tight.
If anyone other than myself can spot the error, it is never sold. In the case of fit, there will ALWAYS be a knife somewhere that fits ANY sheath, so I allow the prospective customer to test fit his knife and if it fits to HIS standards then I will accept 50% of the sale price or LESS only after I have explained it did not meet my standards. Many times I am asked "well where is the problem, show me". I never do show them, but I can still see it plain as day and after all, I did offer full disclosure that there was a problem and reduced the price dramatically. I also give many of these sheaths away to novice makers for them to study if they so choose. So all in all I feel I have overcome the "waste" aspect, and maybe done a little bit of good in the process.
I have always and will always encourage makers, both new and experienced to never fall into the "good enough" trap. "Good Enough" to me is synonymous with perfect (or as close as you are capable). I'm still looking for my first "Perfect" sheath, by the way.
Now you know why when I critique some one's work I stress never selling anything that does not represent their best at that time. I'm sure they are pretty much like all of us........ Their next sheath will be their best, and on and on.
