With another slow winter weekend, I thought I'd add a new thread where your favorite tools can be displayed. My favorite all-time tool isn't particularly safe to use; however, no damages or injuries have yet occurred—and I have two of these mounted on different grinders. Used to cut 'most anything that can be carried to a grinder, this inexpensive blade cuts wood, stainless steel, plastic, rebar, and fiberglass. The manufacturer doesn't recommend using the blade mounted in this manner, but an experienced handyman can benefit from it. OK, enough with the cautions, here is the ultimate blade: Yes, it's six inches in diameter, so it fits the 6" grinder just fine. A home-made arbor attachment-piece will need to be fitted. (I cut PVC pipe, and clamped it with the big factory washers that came with the grinder—centering it to the shaft with care). I've adjusted the (upper) safety shield to protect against broken/flying pieces of bolts, chain, and maybe pieces of "cut-off wheel". Still, tiny particles escape the shields, so wear eye protection. Don't use for cutting fabric, fiberglass cloth, Kevlar, or anything else that can be "grabbed". Even cutting plastic is a very noisy operation, so ear protection is unavoidable. "Mileage" seems to be measured in seasons—and I use it every day! My least favorite tool is the one pictured below, mostly because I have no idea what it is used for! The hook parts operate with the grips, and appear to grasp something slid onto the tapered cylinder of about 5/8-inch diameter. It is factory marked with "Dean": I've even stumped an engineer with this one!
