The double adjustable OHTO Conception 0.3 8

OHTO Conception 0.3

Today: a mechanical pencil I ordered in October. I planned to do a review for a while now and it was supposed to be released today, but the day before yesterday Jeff Abbott released a review of this pencil at the biggest stationery blog of them all, The Pen Addict.

He said all and more I could have said, so change of plans then, I only post a short review of this mechanical pencil, but talk about why I like sliding sleeves, again.

Sliding Sleeves

I don’t know why sliding sleeves are such a niche. In my imagination drafting and technical drawing is done on a computer, so there’s no point in having a rigid sleeve/pipe around the lead so that you can use your mechanical pencil more precisely with a ruler.

In my imagination most use mechanical pencils for writing, at least when we talk about today and when we talk about Earth. Of course there will be exceptions, too.

When writing with a fixed sleeve you have to ‘click’ after you used up the 0.5mm or however much you have advanced the lead.

If you have a sliding sleeve it will retract while you use the lead, so you will have 4mm or more to use up before you need to advance the lead.

If you use soft leads (I don’t) the advantage gets even better than with hard leads because you use the lead p so much faster.

The OHTO Conception

Most of my ideas about this pencil can be seen in this video:

 

In short: You can adjust how far you want the lead to advance and you can adjust whether you want a fixed or a sliding sleeve.

That’s a lot of value for the $15 I paid on eBay. Unfortunately the pen is not available for this price anymore. As far as I can tell OHTO doesn’t have an official presence in the UK, so I wonder whether all OHTO pens here are grey imports anyway. If they are I certainly didn’t have to feel bad for buying it for a good price from Japan instead of buying it for a higher price from a grey importer in the UK.

With 23g the pen’s weight is pretty average for a pen with a metal body and slightly heavier than your average pen with a plastic body.

You might remember my table with the force needed for different sliding sleeves. Well, the OHTO Conception, at least my 0.3mm version, is a bit difficult to place in that table. When I first checked I got a very good value, 5cN or even better, but when I checked another time, after the pencil was in fixed sleeve mode, a force of four time that was needed. It seems that changing from sliding to fixed sleeve mode and back will not always put the sleeve in the same state. Sometimes you then have a ‘better’ sliding sleeve, sometimes a ‘worse’ one.

Conclusion

A great pencil, that could do with a bit more grip. I only wish I had bought another colour.
