Milwaukee came out with a new compact knife sharpener, model 48-22-1590.

It’s a simple tool accessory with a very user-friendly-seeming design.

There are two v-shaped pull-through sharpening slots, one with coarse carbide blades, and the other with fine ceramic blades, and also a fixed diamond rod for specialty blade sharpening.

A large finger loop helps provide for a secure grip, and there’s also a lanyard loop for tethering.

Milwaukee also built the sharpener with a magnet for an additional and convenient storage option.

The sharpener can be carried in a pocket, or attached to gear via a lanyard or tether.

It’s for products like this that I wish I had a window into the design process and decisions.

A compact knife sharpener? Milwaukee Tool?

I wouldn’t have guessed that something like this would be on their roadmap, but at the same time the sharpener looks like a compelling buy.

There are plenty of pocket sharpeners out there, but this one’s different.

None of the other popular models I’m familiar with have finger loops. Or a magnetic for pointing purposes. Some have lanyard holes, but they’re itty bitty.

It’s almost as if someone on Milwaukee’s product team is a backpacker and wanted some useful on-the-go features, and then someone else who’s avid in the workshop, yard, or garden expressed interest in added storage options.
