As much as I LOVE my Camp Tramp I don't consider it a chopper. The Tramp is a wonderfully balanced and attractive general camp knife... maybe one of the all time best. You get a lot of knife out of a relatively light package. I have the same feeling about the S6.
I view my Tramp as a great generalist that "can" chop. The Chopweiler should outchop the Tramp by a good margin.
The SARq may surprise you as it is blade heavy and you can really "snap" the blade. I would guess that the SARq and the Chopweiler will be fairly close with the SARq having a slight edge.
Can't wait for the test!
