Review on 🔪 Klein Tools 44138 Replacement Coping Blades, 3-Pack, for Folding Utility Knife No. 44218 by Mark Hamblin

This is not Klein USA/Germany and they want you to buy replacement blades FREQUENTLY. 444 and 646 MCM dull these blades in no time. Think - the first line, just out of the box. I thought it was just a bad blade, but the pack of replacement blades I tried dulled just as quickly. I can only surmise that the positive feedback from people shooting "ten million leads and it got sharper" ripped the soft wire inside the case. 4/0 or less is fine for a while. Manila rope quickly takes the edge off these blades. Don't expect to cut plastic cable ties with these blades for long periods of time. The low price of this knife tempts you to buy replacement blades. often when they get blunt, you're an idiot. If you buy this knife, get a Lansky Turn Box and be prepared to sharpen FREQUENTLY. The resulting edge is better than the factory edge but still dulls quickly. I suspect these blades are heat treated. (annealed) to ensure you need to replace them more often. You'll find that the tip bends fairly easily without breaking. 440 steel has never bent so easily.
