I bought a delica Wave a long time ago. I actually liked it a lot, although I could never get used to the look. I would definitely recommend it as a great sub-$100 folder though.

I ended up giving it to my best friend who was somewhat new to knives. I also recommended that he get a ZT 0350 because he was looking for a knife to replace his broken Kershaw assisted opener (can't remember which model he had, but it was old and cheap.) That started a chain reaction. He bought another 0350, 2 0560s, 2 0550s, an 0300, and a sage 2. He ended up giving me his extra 0350 and 0550.

The wave feature is definitely cool, but takes a little while to get right.
