Hello, 
I'm trying to find an article that deals with the both the practical and esthetic design aspects of knife sheaths....not a "how-to" article or tutorial. 
Something that discusses pros/cons of different sheath shapes, different belt attachments, different hold-downs (i.e. button straps, pegs, etc),etc. 
Pointers as to finding the balance point between making something super durable and something pleasing to the eye (leather thickness, welt width & thickness, size of holddown straps, etc.) 
And ideas on how to marry the correct sheath design with the knife type and usage. 
Cheers, 
Roger
