Support BladeForums! Paid memberships don't see ads! Rambling warning! I was (probably still am) a modern folder guy until recently but switched to traditional carry lately. Although I still love good frame lock knives, what I grab and put in pocket is a traditional knife. Here, just out of curiosity, I compare a couple of small knives I like, a modern frame-lock production knife and a traditional slip joint (with liner lock) knife, to find out why I choose a traditional carry. So this is a research in my personal preference and not to be generalized. Anyway, these are the two knives for the comparison. Specs: Code: Overall length: 165 mm (6.5”) 175 mm (6.89”) Closed length: 94 mm (3.7”) 95 mm (3.7”) Blade Length: 73 mm (2.875”) 80 mm (3.15”) Blade thickness: 2.75 mm (0.108”) 1.93 mm (0.076”) Blade width: 20 mm (0.79") 15 mm (0.59") Edge thickness: 0.5 mm (0.019”) 0.18 mm (0.007”) Edge angle: 20 DPS 20 DPS Blade material: CPM-S35VN 1095 (carbon steel) Blade grind: Flat grind Full flat grind Handle thickness: 10 mm (0.39”) 12 mm (0.47”) Handle material: Titanium (bead-blasted?) Osage Orange cover, brass liners Weight: 75g (2.65 oz) 78g (2.75 oz) Lock type: Frame lock Slip joint with liner lock Deployment method: Front flipper Nail nick Pivot type: Ball bearings (caged) Direct liner contact They are both great knives with their own goodness and shortcomings. Pros: Code: 1. One hand opening. 1. Thin blade. 2. Pocket clip. 2. Thin edge. 3. High-end stainless blade steel. 3. Narrower blade. 4. Open construction. 4. No accidental opening. 5. Can be disassembled. 5. Edge protected when closed. 6. Durable handle material. 6. Natural handle material. 7. Better finish (modern machining). 7. Double locks. Cons: Code: 1. Thick blade stock. 1. Two-hand opening. 2. Thick edge. 2. No pocket clip. 3. Edge too accessible when closed. 3. Carbon steel blade. 4. Potential accidental opening. 4. Pinned construction (no disassembly). I like the ease of operation of Feist (and other modern folders). But there are two things annoying me. First is the ease of opening. I had it open accidentally in pocket, multiple times. It too happened to other modern folders, of which blades are kept closed with the detent ball. In contrast, I am pretty much worry-free with a slip joint knife which has a strong spring like the GEC. Second, the blade is not slicey enough to me. Feist has a relatively thin blade, but still it is way thicker than most of traditional blades. The edge is also thick, which is typical of modern folders in general. Once getting used to the cutting ability of traditionals, it is very hard to go back to modern blades. I am a bit tired of chasing a slicey frame/liner lock knife...... The GEC doesn't offer a pocket clip nor one-hand opening, which I thought absolutely necessary for a folding knife. In truth, I find them really unnecessary in daily cutting chores. To sum up, in my case, the cutting ability and the secure blade closure are the main reasons to choose a traditional slip joint over a modern folder. Would you choose a traditional over a modern folder, or vice verse, and for what reasons?
