Staedtler Mars Technico Lead Sharpener (502)

It works and does not tend to break the leads. It is well-made and makes it easier to use mechanical pencils. Quick and efficient. Can be used professionally.

These are really effective ONCE you learn how they work. On the box are two - and only two - very cryptic thumbnail illustrations; these are the only " instructions. HOWEVER, a quick dash to YouTube turn out a host of very informative videos on how to proceed. So . . . My verdict is five stars and a strong recommendation for better INCLUDED instructions

Works great for sharpening 2mm leads. Easy to sharpen leads. I'm not sure how to empty it. I do recommend if you need 2mm leads sharpened.

I love how this sharpener has two point options, one is your pretty typical point which is great for writing and drawing. The OTHER option is P O I N T Y, super delicate work because the moment you make contact with paper that point is crumbling into oblivious, or I just don't know what I'm doing.It's very easy to use, drop lead into either hole, shove whole pencil in whole, give it the whirly twirly, and use the white sponge thing to retract led and clean tip. Then proceed with your pencil stuff.

The sharpener is designed to sharpen a specific mechanical pencil. I modified the sharpener to accommodate all my various pencils. Works perfect never breaking the color leads.

never know exsisted amazing

If you have a rotring 2mm lead holder this won’t work. The holder won’t fit into the device.

I returned this so I couldn’t get it to work the way I expected it should
