Handle materials.
Lets get two to four types by a popular vote!
Micartas
G10s
Cord wrap (some one ELSE gets to lead THAT $&@%**|€|£*{£ mess!)
Colors
Type of micarta if you vote that way.
I'm big on OD green G-10...but any darker earthy color is good with me. I'm also like natural canvas (brown) micarta, and it's one of the least expensive.
Never been a fan of cord wrapped handles.
How many knives can be made in two days of instruction?
Probably one, especially considering the number of participants vs number of grinders and equipment. If one has no previous experience it may even be somewhat difficult to get even one knife ground and handled.
Honestly I'm willing to go just to watch people grind or help out if at all possible. While I'm new to this and don't know much, I do have the tools at home to make knives, unlike some others that may attend. I wouldn't want to take up time on a grinder when someone that doesn't have the tools at home could be using it.
I was more our less trying to figure out how many participants it might be limited to, or at least how many people might be able to complete a knife. If only one knife will be completed amongst the entire group it might be hard to justify the time for many guys. If there is time enough for 10-20 guys to complete one knife each, then it would be worth it for everyone. Anyone expecting to make more than one knife for themselves is just being greedy.
