"Wide-line" sharp tips do not burn as fine as the fine-line sharp tips, and tend to give a shallower texture/impression. They make a very good texturing tool as well and being able to burn fatter lines.
The straight, blunted blade allows these tips to sink into the surface and travel in a very true direction, burning a very neat line.
Examples of use: Fatter letter outlining, edging, decorative burning, texturing and animal work. They can be used on flat, curved, turned and carved work.
