Can a knife be this sharp?

Question

im going to a sleepaway survival camp and i need to bring a pocket knife sharp enough to cut through thick vines. Is it possible for a pocket knife to be that sharp?

Answer 1

It can be that sharp, I'm not sure a pocket knife can be that large.

A pocket knife may not be the proper tool for cutting thick vines.

Answer 2

Sure is!

If you put a fine edge on a quality high carbon blade, its even possible to cut another blade with it. The strongest high carbon steel will slice through ALMOST any thing when properly sharpened. Expect to shell out considerable $ when shopping for one though!
