One of the things that distinguishes amateur woodworking from serious projects is sanding. If you’re willing to spend some time smoothing the edges, a do-it-yourselfer can make decent looking bookshelves without getting into any fancy joinery tricks. Sanding is also a prerequisite if you want to paint your project and have it not look like yard sale junk. But sanding is a huge time drain, and it’s hard not to blame a guy for skipping it. A new piece of hardware is intended to eliminate that step without diminishing the final product: The ominously named Final Cut blade sands cuts automatically as they’re made. The heavy-duty table saw blade has discs of sandpaper affixed to either side so that it power-sands as it slices (replacement sanding discs are available without the blade). Not only does that leave users with clean pieces of freshly cut work, it also allegedly cuts down on “kick-back,” the dangerous moments in which a board is pushed backward when it hits the saw incorrectly. Looking over sample cuts made on moulding, solid wood, laminated sheets and composition board, it’s hard to believe they came straight off a table saw. At $75 per blade, the FC isn’t cheap, but it’s not much more than high-end discs made by Ridgid and Craftsman — and that difference will seem pretty trivial if woodworkers suddenly find their projects taking far less time than they once did.
