When you first start out, everybody wants a knife. Your wife's Uncle Ernie wants one, heck your wife wants you to make one for her dad, brother, brother-in-law....darn, even the missus is against ya!
There are couple of things that you can do...
If (or rather when) this happens, tell this person that sure, you would be more than happy to make a knife. Be sure to tell them of the material cost. They will then of course offer to pay for the materials, I mean its only
fair. Now this next part is very important.
Tell them that if they want you to make them a knife they HAVE to be there the WHOLE time you are working on it, from start to finish. They will ask you at some point how long it will take. Be honest.
Now, its not too late with this last freebie you committed to. You can ask this last person if they will come over while you are making "their" knife. Oh, yeah, explain to them that there is no beer drinking while working with sharp, pointed objects. If they are busy at the time then tell them to "let you know" when they are ready so you can get started on it. Then go enjoy yourself a beer.
One other thing, if you do end up making a freebie, don't put your mark or name on it. Lets say years down the road you become a well known maker. No one can prove that its one of yours. Besides, what do they expect for free...all they wanted was a knife, right?
