Well. I'm not wealthy- so cheaper knives than most of the pretty stuff further up thread. I use knives to work outdoors a lot, inevitably, some will vanish. Stuff happens... Like snow, we have a lot around here. If given any chance, it EATS things. Your co-worker drops your tool off a barge in a freak accident, clearly not THEIR fault- or just "forget" to give them back. Here are a couple of Chinese ones off of Amazon, Eafengrow. I will buy clones if they have the decency not to fake trademarks, brand names, counterfeit packaging. These come in a plain black box with model # and maker's brand name only. Sharp OTB. A usable tool for around $25 US. They are marked as being D2 tool steel on the blades. See the XRF gun analysis below each picture for more about that- The yellow one is a new replacement for another I had, the same model knife but with orange scales which I recently had disappear. Both models are well made, take a good edge. BUT: the orange handled lost knife AND the larger orange handled knife shown below were softer steel than the new yellow handled one. Very different response to sharpening, it required way more work to remove steel on that yellow one. Got me wondering, so I asked the guys at the scrap yard. They're knife guys too, didn't even charge me for the tests. I find interesting the suggestion by the XRF unit's software that first tested alloy is "cronidur 3"(cronidur 30 is a stainless steel used for bearings?). The guy running the business looked at the first reading (yellow knife), ignored the screen note of "cronidur3"and said it was probably 420. The second (orange) knife, it read a small % of Ni, otherwise, pretty close to the first. Device called it as "SS 410/16". The lack of Mo and Si suggest neither blade is made from D2.
