Great feel, nice writer and beautiful quality.

I bought the Scribedriver Pencil to match the pen. I was reluctant to get it because it uses 0.5 lead and I tend to break 0.5 lead far too easily. The mechanism that holds to the lead is very rigid so that doesn't seem to be a problem. Writing with it feels very nice, it's balanced, and the knurling is comfortable. However, it somehow still feels rushed or that they didn't think about everything.

The lead can be advanced either with the top button or the LTT knub on the side. The top is easier to depress but feels a little mushy. The knub reaches tension in the middle and it quite stiff, leaving a deep indentation in my thumb. When trying to quickly press it it 2-3 times, it's difficult, to the point it's almost useless since the top is present.

Before it came out I purchased the Zebra M-701 0.7 pencil. That pencil has the ability to remove the cap and use a very small eraser that works fairly well. The LTT Pencil does not have an eraser. As such, get good. If you mess up, you'll have to bring an eraser as well. For a student, that's workable. As an every day carry in a pocket, no so much. While the Zebra feels noticeably cheaper, it also matches it's price at about 10x less than the LTT pencil.

This is a really nice mechanic pencil. It goes well with my leather note book and it pushes out just the right amount of lead unlike many others I've had. I like the weight of it too. Its not too heavy. Overall a very nice use of the screwdriver shaft rejects.

Been using my pencil, and I for the most part have had no major issues, works well.
As for the minor issues, the first is due to the mechanism they used for the internals of the pencil. This mechanism does not retract the tip back into the shaft, so you need to always be aware of the point of the pencil so you don’t stab yourself. The packaging was well thought out to protect the tip from damaging during shipping in the box.
The second minor thing doesn’t weigh on my rating, there is no eraser, which is fine for this product, I actually prefer that after using it, just be aware as the fact isn’t listed on the product page
.
My third minor issue is what dropped it down a star, they can definitely fix this issue without a major revision or significant cost change. The click/travel isn’t satisfactory, be great if it made a noise but my issue is related to the spring at the top. The spring is not stiff enough, when you depress the top, it can move somewhere between 1/2 to 2/3 of the travel distance without engaging the pencil mechanism. With a stiffer or longer spring, the clicking would be uniform. If they fix this on future production runs then I can recommend it as is, if not, maybe consider ordering a set of pen springs online after you try it out yourself.

I love this pencil.
At first it felt worse than my Staedtler Mech Pencil but with time, I grew to like the the LTT Mech Pencil just as well. As I kept using the pencil, I liked it more than the Staedtler.
My only complaint is that the clip is on the "wrong side" of the Lever" for a right handed user.
The core of the issue is the weight. The LTT Mech Pencil is heavier as expected due to the the materials, which take a bit of time to get used to when you have been using a lightweight Mech Pencil for years.
Overall however, this is a must have Item!
