Hey Spidey,

For a "scary sharp" edge I have been using "self adhesive" sandpaper in 15 micron, 5 micron and .05 micron grits from Lee Valley [I have to learn to stay OUT of that store!!!]. I stick the sandpaper on to a sheet of plate glass and use it as a final honing - does the edge ever shine! Great for plane blades!

The problem with regular steel scraper blades is that the fiberglass fibers are harder that the steel and dull a steel edge very quickley. carbide blades are harder that the glass.

Take a look at the Sandvik carbide scrapers at Home Depot. The blade is about 2" wide with a slight rocker [about .040]. Since I bought one I have not had to bother sharpening a scraper. I have used [and abused - scraping metal] the carbide blade for quite a while now and it is still usable. I paid about $14.00 Cndn for mine. There is a two-handed version available but I have only seen it at Lee Valley for +$30.00. Replacement blades are available.

The term "scary sharp" is used often now - I first heard it from my son when he was about 4 years old. Kenny was in my workshop and I was showing him a wood chisel. After Kenny seeing it cut through spruce with out any effort he described it as "scary sharp". I asked him what he meant by "scary sharp' and he said it was "so sharp that it could cut you and you would not even feel it - you would just leak blood". Good description in my books!
