Those are the same as Snap-on. The texture may have been altered a little but Williams is owned by Snap-on and Williams only started these under their name after Snap-on Introduced the Instinct line. Initially the pattern was dropped from the main SO line until demand generated a reintroducing it back into the line and at that time started pushing the colored handles.
Snap-on has a long history of retiring a pattern only to resurrect it under another brand. Done it with Par-X, Blue Point, Williams, and some of the other Snap-on brands. I think it's a pretty a very smart move. The tooling is done and paid for, the non recurring engineering amortized, the design proven and revisions for cost savings, product enhancements, warranty claims, etc already done.
If you are willing I'd like to see close ups of the tips.
