I am wondering if there are any alternative ways to sharpen the tungsten without the standard grinding wheel. I have very limited garage space and at the moment I use a grinding wheel (dual discs) that I squeeze into the vice so it sits firm, then grind. I dont have the space on my workbench to attach the wheel there permanently. Ideally a tungsten sharpener would be nice, but for my amateur/hobby usage they seem too expensive. Is there some other smart tool or way to sharpen the tungstens?
