What's a good angle for a swivel knife blade?

So I sharpened my swivel knife blades and I feel like the cut should be a bit wider and I may have sharpened it at a low angle. What angle to others use when sharpening.

60 degrees I believe is the optimal angle.

Leather Wranglers recommends 30 degrees. I have a Tandy and one of Leather Wrangler's swivel knives and the angles on both are almost identical.
