As other folks have mentioned here, “mid-range” and other price tiers are mostly relative to the user, his financial situation, his allotted budget for knives, etc. That’s perfectly fine. For some folks, maybe the Endura 4 is mid-range; for others, it’s the Inkosi.
While price generally has a directly proportional relationship with quality and longevity, some mid-range knives challenge this, and that’s why I have a healthy respect for certain mid-tier knives. I’ve had my Endura 4 since 2012-ish and it’s still going strong. The Emerson LaGriffe has also held up well through the years. I’ve only recently acquired Tri-Ad knives and time will tell if they stand fast. Again, is an S35VN blade in G10 handles mid-range? That’s up to you.
Nonetheless, from one knife bro to another, do invest in a knife of substantial quality, not a throwaway ones that can get you hurt. Cheap knives are costlier than expensive knives. Get something that will last and withstand the daily tasks you demand of it.
Bottomline, it’s great to own high-end knives, but I also wouldn’t write off mid-tier knives. There are a handful out there that are rugged and reliable.
