Hi everyone, just bought my first Benchmade. I purchased it from a local dealer and I've been playing with it all night. I got the 555 version and I LOVE IT. That is until I looked at it closely and I realized that it's an older version and has the 440C blade on it. Now here's my question to all your blade steel experts should I just keep it? Or do I take it back and go get the one with the updated steel? Are there advantages to the 440C? I just feel like if I keep it, I'm missing out on getting a steel upgrade, especially since I paid the same price for it. I hate when an impulse buy goes wrong! :grumpy: So, what do you think everyone? Keep it? Or take it back and look for the 154CM one? Is Benchmade's 154CM really that much better?
