I own many knives and have reached a point in my collection where I want to purchase a knife in the $500-$750 range. I'm am curious as to your opinions - Chris Reeve, Medford, Olamic, or ????
Thanks
Good question, OP. Candidly speaking, I have owned (or still own) knives from every maker you've listed, as well as some of the others in this thread. I will say that Olamics, CRK, Medfords, Hinderer, Shirogorov, Koenigs, Zieba, among several others are all strong, solid choices when you're feeling ready to step past the standard production knives from the likes of places like Zero Tolerance, We, Reate, and many, many others. I also recommend taking a look at Spartan Knives, the Spartan Harsey Folder is a phenomenal knife that comes in many really cool patterns. Andre Thorburn's another good one to look into.
All of those I've listed above are going to have superior fit, finish, better materials, and that intangible "something" that lets you know that your knife is special, and worth more because of it. In most cases, those knives are all small batch made, if not outright custom. Many of their designs are VERY different. For example, a CRK Sebenza 21 is a fantastic knife....but it will be physically smaller and weigh about seventeen lbs less than a fullsize Medford Praetorian, which is also an excellent knife. Olamics come in a dizzying array of customization across a few different models, and they're beautiful, and functionally great. Shirogorov knives are fantastic in fit/finish, and flipping mechanism, though the prices get entirely out of your price range for any but the most basic models. $750 will get you into pretty much any Hinderer XM-18 or XM-24 you might want, though and you'll be able to customize yours with lots of aftermarket hardware.
THAT SAID.
If you fall prey to the sickness like some of us, you'll want to keep in mind resale value. To be entirely objective about it, knives from CRK, Shiro, Hinderer (to some extent), and Koenig are going to hold their value better than knives from Olamic, Medford, Zieba, or a few others. This is not a slam on them, it's more an acknowledgement that some makers make knives which are stylized in such a way that only certain people will want them. If you head over to the Exchange, and look around, and start to keep watch, you'll get a better idea of what moves and what doesn't (without a few rounds of discounting).
At the end of the day, an expensive knife won't cut any better than a $40 Buck 110, but at least you'll have something that brings you joy, and appreciation for very well made things. Good luck and let us know what you go with!
