### ⭐⭐⭐⭐ great little tool
*by A***R on March 21, 2019*

well packaged, used for hobby.

### ⭐⭐⭐⭐⭐ NOT for #18 Blade replacement. Blade dimensions are on package,
*by B***E on January 10, 2018*

but not on Product Display page so I submitted return/refund request. Dimensions: Cutting edge width 8mm, blade thickness 0.55mm, tang width 6mm, LOA 36mm. Blades are superb OLFA Japanese quality. However, was seeking OLFA replacement for USA-made Excel #18 1/2" (13mm) Chisel Blades which I subsequently purchased. These little guys are not even close to a #18. Cheers!
