I read in earlier posts that they make these auto spikes with heat-treated steel and kick-ass springs. And the ripoffs are using aluminum handles. But right now I see on 1sks the one listed under "SWAT-GF SWAT Guardfather Automatic IcePick" also has Aluminum handle. So, are those also ripoffs or SWAT changed the material? How's the quality of these spikes selling on 1sks?
