Anyone know if the Sven brand and Sawyer brand of camping saws allow replacement blades to be interchanged between the brands? I see a 15" and 21" size saws for both companies and the blades look very similar with two holes on each end of the blades. For some reason I have a replacement Sawyer blade(Trailblazer from Sweden) I found, but no saw. I like the Sven saw more and was wondering if this Sawyer blade would work on the Sven before I order it from REI. Thanks for any help.
