My new TB combat grade easily shaves off the hairs on my arm but I cannot get my new SAR 8 SE to do the same! Am I crazy to mess with this? What is the likely reason one will and one will not shave? I finally took the SAR 8 to a brand new butcher's steel and then stropped it on my Filson leather belt. Still very few hairs coming off with the SAR 8. Any thoughts?
