Spyderco has so many different knives in that price range or below, it's more like which one do you like?
You could buy the discontinued Stretch model, the classy frame lock Volpe, or save yourself $30 and get a ZDP 189 Delica in SE or PE. The regular enduras or police models are still classics and still sell very well for good reason.
For sure there's something for everybody. If you wanted to spend some more I would definitely suggest the military in the BG42 sprint version. IMO, one of the best production knives from any company. As well made and well balanced a knife as you can find, with BG42 steel. There's not many of those left. The classic military in S30V steel is a great knife also, and closer to your price range.
If it was me I'd go for the ZDP 189 BRG delica, and buy a Byrd knife with the money left over. If you need a tank of a knife, the manix or mini manix won't let you down either though. Joe
