With each depression, the #21 tip forms two halves of a raised scale. This design allows for slight variation in scale size.
Heavy duty cord is recommended for all scale tips.
Useful for smaller projects like songbirds or smaller mammal carvings.
"Wide-line" sharp tips are used mainly for feather and hair detail. They do not burn as fine as the fine-line sharp tips, and tend to give a shallower texture. This is the style of texturing preferred by many top carvers including Larry Barth and Pat Godin. Used in much the same way as Round Skew tips (Series 7), but yielding a wider detail line.
Heavy duty versions yield a slightly thicker line than standard versions.
