Comments about Johnson Insta-Mark Mechanical Carpenter Pencil - 3400:
After careful observation, I noticed that ordinary carpenters' pencil need to be sharpened about four times an hour. This sharpening takes about 90 seconds, or six minutes per hour, fully 10% of the work hour. At a modest [$] total cost of hiring a professional carpenter, the savings of using a "Johnson Insta-Mark" over a typical carpenters' pencil amounts to about [$] a day or an incredible [$] a year for each carpenter hired - all this for a [$] investment per carpenter.

I use mine all the time. The only complaint is that when I clip it to my shirt it falls out. Other than that, I would not / could not do with out it. No more ruining knives trying to keep the traditional pencils ready.

I purchased 2 of these pencils 6 years ago. I liked them so much I looked every where for more. I had to go on line and find your product. I brought 6 pencils and gave 2 to friends. These pencils are great and they work in all the diffcult spots other pencils can not perform. I don't know why they are not available in our local hardware stores. These pencils are easy to use and don't need to be sharpned and carry there own spare lead. My 2 friends loved the pencils.
