I don't usually bother trying to change someone's opinion. But I'll throw this out there OP. You're takeaway closing statement is grossly misinformed at best.
FWIW, the 2 Spyderco's you have experience with are 2 models made in China. They are entry level models with budget steel types. So when you compare them to a blade with CTS-XHP steel, you should see significantly different results. Different steel, different blade geometry, different lock types, etc...apples and oranges.
Enjoy your knives. Just wanted you to be aware there are a WHOLE LOT of comparable choices out there that are up to a lifetime of reliable use and abuse.
no, I don´t think there are a "whole lot", especially for the same price. Look at the AK-47 now, CTS-XHP, one of the strongest locks or strongest, great ergonomics, pommel, just over 5oz, thumb disk (w wave opening function), 3.5" blade for around 100 bucks. Where are there a "whole lot" of knives that can compete with that.
