Well I can buy Code4 from local hunting gear store. So I can inspect the knife before making a purchase.I think the most important thing to consider would be buying the knife from someone you trust and someone that will take returns. Bought a CODE4 a few years ago and it was a gorgeous piece of work with a wicked edge on it. But... it felt like they had poured sand on the pivot before assembly. It ground and grated pretty badly, and no matter how much flushing and blade exercising I did, it wouldn't quit. Since I was going to use it as a lightweight kind of work knife, I was also concerned about the smooth scales and thin frame. To top it off, the Triad lock was so stiff I had to work to close it. Back it went.
My nephew wanted a "good knife" so I decided on the Mini Grip. Waaaayyyy too small in the hand for me, but then it wasn't for me, it was for him. (I can cover a Mini Grip in my palm.) This was purchased at a time when BM was having sporatic quality control issues, so I looked at 3 - 4 to get one that lined up right, had good grinds and smooth action. He loved the knife, and since it was his ONLY knife, he worked it hard. He is an outdoors kind of guy and he used it daily. After about a year the lock had a fair amount of play (never came unlocked, though) and the only thing he didn't like about it was for bigger work on his property it was a bit small. I told him to contact BM to see if they could tighten up the lock since it moved enough to make it click, and they told him no. Now they did tell him that if it FAILED, they would repair it if they accepted the circumstances of its failure. I thought that was a stupid response, but then I think of all the guys that try to baton with a folder, spine whack the crap out of them for "testing" purposes, and all manner of other idiot stuff. So, OK. But then, about six months later he lost it.
It brings two things to mind. What are you going to use the knife for and who you buy it from. I have several CS knives and use the crap out of all of them, and thankfully, haven't needed anything from them. I hope if that day comes that GSM has their warranty situation sorted. I heard from a friend of mine that they will honor the warranty on a CS knife IF you have proof of purchase. He didn't, I don't, so if one breaks I might be screwed.
Planned use is making sandwiches at work, opening food and similar, and carrying for more formal occasions.
I have enough fixed blades to never use a folder for outdoors stuff.
Having spare parts is good, but IDK how well would that work from Croatia and how would it go with shipping and everything.
Then again, from what I heard - Cold Steel just ignores your emails LOL
