Premium Sandflex Hand Block for Woodworking & Metalworking - Fine Grit Abrasive Tool for Smoothing & Finishing Surfaces - Ideal for DIY Projects, Carpentry, and Metal Crafts

I purchased the 3 pack. So I'll be reviewing all three at once. I had a scratch on one of my beloved Spyderco pocket knives. I wanted a way to remove it easily. I did some research online and came across these. They are a dream come true. They are some of the most useful things I've ever purchased. They remove rust, they remove scratches, and they can even be used to clean odd things like rubber. These are an alternative to using other products like, sandpaper, emery cloth, steel wool, polishes, compounds, pastes, files, brushes, scrappers, and buffers. With these you can toss all of those in the trash. You'll achieve better results with these hand blocks. When you use the coarse you'll leave your metal with a satin finish. Or if you just use the fine you'll leave only a shine. I've used these on every knife I own with a satin finish (over 30 all together) and some I gave a satin finish that did not have one before. They all look gorgeous and they all have that fine mirror shine to them. All without me using any polish on them. These blocks will last me a lifetime. I've used them allot already and they're barely showing any signs of wear. Well worth every cent, and then some. If you need to remove rust or scratches from your steel. Look no further. These are the hand blocks you're looking for.
