I picked up a few microtech knives in a trade and I really have no idea what they are worth. Any microtech people out there that want to give me an idea of what to ask for them? All are supposed to be unused but the red one does have a tiny scratch on it. The red one is a 8/2015 date and the black one is a 10/2018. Both are utx-70 variants with the elmax blades.
