## Description

Stealer Mars Technical Lead Sharpener

Review: Great sharpener, but needs better instructions! - 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
Review: A sharp idea. - 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.

### ⭐⭐⭐⭐⭐ Great sharpener, but needs better instructions!
*by J***R on July 2, 2025*

### ⭐⭐⭐⭐⭐ A sharp idea.
*by A***. on July 17, 2025*

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.

### ⭐⭐⭐⭐⭐ Pointy or POINTY
*by K***N on April 1, 2024*

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.
