I tried these and they haven't wasted any lead at all

Thinner lead is a pain

Pentel still makes the best mechanical fine lead pencils.

Between the brass clutch and the sheer durability, this pencil feels excellent to write with with no lead wobbling

Since I've got these, these have been my favorite lead pencils since

Got a soft spot for these--love the color and the number nine is lead is great for kids because thicker lead=less breaks

My girls tried my 0.7 lead and my 8 year old did pretty well with that, but my 6 year old kept breaking it

Thinner lead is a pain

They are admittedly unforgiving when you drop them on the ground; the metal piece at the bottom, out of which the lead comes, can bend after being dropped, causing the lead to break quickly as you advance it, after that happens

I've also been using the same lead pencil religiously for 2 years now and it still works as if it was brand new
