Hey Jarrett. Love the knife BTW. Whenever any material you're working with clogs belts, this is especially true for Ironwood, spray the belt with WD40 when it is new, before starting to grind with it. It won't clog after that.
I love the Ivory micarta, but it is tempermental to work with compared to the easier phenolics. I think the results speak for themselves. I get mine from Sheffield also.
