Genetic Changes. Mutations in the ATM gene cause ataxia-telangiectasia. The ATM gene provides instructions for making a protein that helps control cell division and is involved in DNA repair. This protein plays an important role in the normal development and activity of several body systems, including the nervous system and immune system.
The Best OTF Knife â Blade Types. OTF knives give you added access to your blade, when you need it most. This type of knife uses a assisted opening mechanism to fire the blade up and out the front of the knife handle. OTF knives come in a variety of blade configurations.
Coarse (13 tpi), medium (17 tpi) and fine (25 tpi) blades are available. The coarse-toothed blade is a good choice for fast material removal, while the fine-toothed blade provides the best performance in densely figured wood or for leaving a finely grooved surface for veneering. The medium-toothed blade is a good general workhorse, offering a compromise between speed and tear-out prevention. Designed for our bevel-up planes, the blades come in three widths. The 1-3/4 blade is for our small bevel-up smooth plane and the 2 blade is for our low-angle smooth plane.
