This is what we use when you send in battered old shears and secateurs with nicked and chipped blades the #120 side eats through the steel to a new edge, then the #300 gives a crude finish before moving over to a whetstone to get a decent edge. Use dry. Indispensable. Essential for fixing damaged blades, but also useful for sharpening rough edges like mower blades. 50g 217 x 18

Good to average purchase but they work.
Item Package Quantity: 10, Color: Green
Magnetic hooks are well made, the hooks have plenty of strength. The magnets on the hooks aren’t quite as stout as they should be, but all in all they were a good buy.

Great holding capacity for hand tools
Item Package Quantity: 6, Color: Orange
I needed to add space to my workshops metal shelves and these are perfect for hanging hand tools around the metal bracing. They have enough holding capacity to hang a small sledgehammer. Now I can readily locate tools and allow for more space on the shelves.
