You know I hate to beat on the rotting horse again, but what is with that...dull blades?
None of my Rats were sharp enough for me. The only reason I've been able to think of is that perhaps they keep them a little on the dull side for inexperienced newbies who buy an "indestructible knife" to prevent them from damaging the edge (rolling, microchipping) by using a supersharp edge on a really hard surface to "test it", then trying to return it to the shop as "damaged".
Where-as an experienced knife owner would know to not use a straight razor sharp edge and, I dunno, cut another knife in half with it. An experienced knife owner should have no problem sharpening a knife to the level that they want it, without it being too sharp/too thin edged for the desired task. That's the best reason I can think of. To protect the dummies from themselves. <img src="/ubbthreads/images/graemlins/laugh.gif" alt="" />
Kinda like when you give a kid a really dull pocket knife, and don't have to worry about him cutting himself with it, because by the time he's old enough to learn how to sharpen it, he's responsible enough to know how to use it. <img src="/ubbthreads/images/graemlins/cool.gif" alt="" />
