I have the Pioneer, Pioneer x, and Farmer. All three are Alox aluminum scales. I have yet to buy a plastic handled SAK. How much difference is there is rigidity on heavier whittling cuts? Does the strength of the scales affect your view of the SAK as a survival back up tool? I bought the Pioneer X today because it is essentially the same knife as the farmer, but with more practical scissors instead of a wood saw for edc. I narrowly chose it over the Super Tinker because I like the awl better and the grips should be stiffer. Maybe someday I will try out a Super Tinker, but for the most part I worry about putting pressure on the plastic handled versions. I'd love to hear your thoughts.
