Tronex oval head cutters are great for general use. The ergonomic handles are 4.8 inches, fitting the average hand much better than the smaller tools on the market and allowing for easier repetitive use without fatigue. The flush cutting edge means that both cutting edges receive a tiny bevel by diamond honing over the entire outer length. The bevels are at 60 degrees to the plane of the cutting surface. They are no more than 0.12mm in width and thus form an exceptionally small V-shaped groove along the edges. It also yields only the tinniest raised surface, or pinch, on the cut lead. Recommended for use on soft wire no larger than 16 gauge.
