RS,

I use a long, thin kitchen knife with a serrated cutting edge.
The serrations are gently rounded, rather than being pointy.
I use long, slow cutting strokes and take my time to get a
smooth cut. I sometimes mark the cut lines with a permanent
marker, such as a "Sharpie". Most of the time, I "eyeball"
the cut lines. The key is to use a very sharp cutting tool
that's long enough to make one smooth cut through the foam.

FWIW...

I purchased a nice aluminum case at a hamfest recently and it has a soli
d piece
of gray foam in it. I would like to neatly cut out the shapes of my Bir
d 43
wattmeter and MFJ 259B in the foam. Can someone give me a clue as the b
est way
to do this?

Thanks

RS
