Rootnuke: Keep in mind that everyone does this different & I know of no set rules on Chisels, Scrapers, etc.
IMHO, if the tool is made of good quality tool steel it will simply seldom need sharpening. The FlexCut brand are made of spring steel, very hard & I sharpen mine on a tri-stone sharpener that has Arkansas Oil Stones on it.
As I said, I sharpen them about every 3-4 rifles. They hold a razor edge forever it seems, that is IF you don't hit any metal with them. As with any tool, once ya hit metal on that razor edge, you will have to sharpen them.
I have made allot of other tools & scrapers & some do well, some were not so well. Small old wood chisels made a pretty good scraper. When I heat them I put a heat block paste on the tip, heat them & then quench them in motor oil, so the temper is not messed up on the tips. For tiny scrapers like used to scrape out the slot for the underlugs, as small needle file or small chainsaw file makes a good one. One must take care as not to overheat the end when forming it & not take all the carbon out. If it gets bright red & starts sparking, you just went one step too hot and took the carbon out of the steel.
But it you have to sharpen the tool all the time either the tool is not good steel, improperly hardened, or you are sharpening it wrong. Most carving tools & wood chisels & scrapers, you sharpen on One Side & you leave the other side untouched. The cheap carving tools will get you by at the very least. When you get a good set of carving tools you will appreciate them & make scrapers from the cheap ones. Buy one good FlexCut carving tool a year & in 5 years you will have all of them you really need. (WoodCrafts) The main carving tool you need is the "V" tool.......... You can inlet & carve half a rifle with a "V" tool alone.. Then a couple half round tools of dif sizes & you can really go to town. That and a set of the 5 Nickolson small fiwood files & you are on your way to making a rifle.... I probably have at least 4 sets of carving tools I have bought.... Looking back, if I did it all over again I would just buy the FlexCut as the others sit there & do nothing... Yes the FlexCut cost more money, but I have allot more $ in the other sets combined & I never use the others. I will most likely end up making scrapers from all of the other ones eventually......
As for chisels, I seldom use a chisel on a rifle. I prefer to use band saw, a wood rasps, belt sander & carving tools to cut mine out when making one from a blank. About the only time I use a chisel is when inletting the barrel at the breech & the base of the tang as it is tough cutting straight down & cross grain.
