replacement hobby blade

I have been trying different hobby blades and have finally found one that cuts easily. The brand is Model Master. They mainly do paint for plastic scale models but they also make model making tools. I was at one of my local hobby shops and saw these blades. On the packaging they are described as being honed by hand with a strop and they are made of high carbon steel. The blades themselves are the standard #11 blade shape. They are a dark blue/black. Another feature I like is that when the tip gets dull I can take a pair of needle nose pliers and snap the tip off and keep using it but I have not managed to snap a blade while using it.

Here is a link to an online store that sells them. http://www.hobbylinc.com/htm/tes/tes8816c.htm
