Guys, you can do whatever you like, but personally there are a whole lot of things I'd rather spend the money on than an Incra fence for the Portaband.
My dad is really into woodworking, so I'm very familiar with the Incra brand, and all their products are of super high quality. But I see zero need for that kind of set-up on a portaband in a knife shop.
If a guy is really set on resawing blocks into scales ALL the time, then a quality WOOD bandsaw with a quality fence would make sense. If you're doing it everyday.
I've only clamped a straight edge down as a fence on my Portaband about 4 times ever. I'm all for as many tools as you can afford, but I just don't see the point here.
