I am not going to recommend a substitute, temporary or not. Others have and will do that. But I will recommend that you proceed to Randall's website, order a catalog, peruse the choices, agonize over what you want, and send them a $50 deposit. Get in the habit of dropping your pocket change in a gallon jar. Five years from now, dump out the jar and pay for your knife. You won't miss the money. You'll enjoy the wait. And it'll be your knife.
