Got these (combined with a new steel handle) on a whim because I needed a new handle and had a coupon at a local store. Figured I'd give them a try and see if they were any better than the standard blades and I was thoroughly impressed. They are lasting about 3-4 times longer than the standard blades and only %25 more money, they are well worth the extra cost. Give them a try and you'll find yourself only buying these from now on.

This blade worked wonderfully well for me. It lasted over a couple years and was still sharp when the tip finally snapped off due to stress. I'd certainly recommend these to any modeler (but with the advisory to be gentle with the tip.) I'd also recommend the cheaper #11 model blade too, as it seems to work just as well.

Very nice cutting tool, long cutting life, smooth control.
