I have a Crunch (very handy though not cheap) and the silly scalloped knife is
getting blunt. One of the suppliers has a diamond "cone" which is claimed to be
suitable. Are they any good, any other suggestions, or should I just grind it
back to an ordinary knife blade?
B&Q have a tapered diamond hone (not just a cone, its hollowed one side) that
do the job, but the best system I've seen is from Spyderco. I have a Spyderench
the serrated section of the blade is very useful, as is my Gerber's, so I
suggest grinding it away, if you want a plain section only knife buy one. The
Spyderench comes with a diamond hone as part of its kit, so keeping it sharp
there are quite a few market sharpeners that claim to work on serated
blades. You'll find a few here under accessories
but what I find works best for me are the ceramic rods from spyderco
available from Poolewood, search for ceramic sharpening stones, product code
