If you're buying this pencil thinking the Delguard function works on the 0.3mm
lead size, you might want to turn back on this one. The Delguard "system" in
this pencil only works to a certain extent.
As someone who's used to using 0.3mm in note-writing and drawing, I've used many
0.3mm mechanical pencils and got used to the nuances of 0.3mm pencils (Not
writing down too hard as one would on a 0.7mm, don't advance the lead too far
etc). That said, I bought this pencil just to test out if, with the Delguard
system on the 0.3mm lead size, I can eliminate such nuances with this pencil
just for the fun of it.
With that being said, the Delguard system in the pencil only works to a certain
extent. Most Delguard pencils come with a guide or warning on the package
telling users the Delguard system cannot guard the lead after 4 or more clicks
(or something like that). Unlike the 0.5mm and 0.7mm variant, the length of the
lead advancement was shortened, and the amount of lead advanced after 3-4 clicks
is just about the amount of lead I advance on most 0.3mm mechanical pencils (1-2
mm out of the lead sleeve), which makes no difference in my experience in lead
breakage in most pencils (granted I got used to mechanical pencils of 0.3mm
sizes). The Delguard system works to guard the lead up to that distance, and
after some stress test on lead breakage with other pencils, I can see some
difference in using other mechanical pencils for such lead sizes, but not enough
for me to switch from other pencils that I have already owned (Graphgear 1000,
Uni Kuru Toga etc) which has features I prefer more than the Delguard system.
With that said, the pencil is light and feels nice to write with. It is also a
solid pencil, and I would recommend the pencil, along with the Pentel Orenz
0.3mm, if they face such lead breakage problems. While I may not be in favor of
the Delguard system on the 0.3mm lead size, I would recommend it for users who
have a tight budget.
