If you can't bring the knife back, get yourself a $9 Mora.
I agree.
If I decided to do anything else besides that it would probably be to buy only a full-tang blank and wrap the tang with paracord for a handle. However, that's not something that simply works right out of the box. A mora would work right out of the box, and it would work well. Buy two in case something happens to the first one, and you will still save money over many other knives.
Models 640 or 660 from Ragner would get you a good knife for $7 or $8. See:
