OHTO Super Promecha Pencil PM-1500P

The Super Promecha is the top of the excellent Promecha range. A serious mechanical pencil suitable for a range of uses apart from it's core target of professional drafting.
Bullet-proof build from virtually 100% metal - largely aluminium, with matt silver finish over some brass components. The only plastic we can find is the lead reservoir.
The grip area is 10.5mm diameter and finished in a fine diamond-cut knurled pattern. The upper barrel is hexagonal 8.3mm diameter, set unusually with four rubber o-rings. Total weight approx 19g.

OK, let's get to the feature list:

The all-metal top button contains a lead grade indicator running in 7 steps from B to 4H. Removes to reveal the replaceable eraser and clearing pin.

The clip removes by unscrewing the top of the barrel.

The lead sleeve is fully retractable by turning the grip. It extends up to 5mm for classic drafting uses, or can be set partially extended between 0 and 5mm for writing purposes. This feature makes the Super Promecha reasonably pocket-safe.

Finally, the unique killer feature. The rotary control inset just above the grip adjusts how much lead is dispensed with each click of the push-button - between 0.2mm and 2mm according to preference. Very clever.

Available with four lead sizes:
PM-1503P 0.3mm
PM-1505P 0.5mm
PM-1507P 0.7mm
PM-1509P 0.9mm

We have a huge choice of replacement lead in the widest range of grades available on the internet: See the list here.

For eraser refills, we recommend the Pilot GMSK eraser refill available here.
