Double-Tap Sleeve Technology 

Designed for extra level of safety, Double-Tap Sleeve Technology ensures the safety for both the user and the MICRO CHISEL.

Hard press on the MECHANICAL HOLDER extends the safety sleeve and subsequent light press extends the MICRO CHISEL and another hard press retracts the sleeve back into the HOLDER. It's full retraction mechanism prevents from any damage of MICRO CHISEL when not in use.

Installation Method

Insert the MICRO CHISEL into the MECHANICAL holder thorough the lead sleeve from the bottom. The opposite end of the MICRO CHISEL is in rounded shape for easy insertion into the lead sleeve. 

Comfortable Grip

MECHANICAL HOLDER's comfortable grip can provide great precision when scribing as if they are drawing on a paper. 


  • Do not over extend the chisel from the grip. This may cause damage or break the chisel. It is recommended to click the holder 3 times after inserting the MICRO CHISEL to get the proper length for use.

  • Holding the MECHANICAL HOLDER improperly in low or steep angles will not give good results and may break the chisel. It is recommended to hold MECHANICAL HOLDER, upright, as if you are writing or drawing.

Good for beginners


Well sharpened needle, well made holder


Excited to use my latest purchase!

Omar Majeed
Pricey for what it is

Very nice performing "needle chisel" and has been great for retracing panel lines already present or adding some definition when hand painting details. Functionality aside, I expected something a little more substantial. The holder feels just like any other plastic mechanical pencil. Would have expected something more akin to an aluminum holder from other similar tools. Feels like it could benefit from having more weight to it.
