The generally wider handle makes the SAK a better whittler than the average stockman. In fact, Chris Lubkemann and long been a fan of the SAK for whittling.
It's not by accident that an SAK is on the cover of his
this book.
This is his latest book and he has an SAK on the front cover of that one as well.
I've always found that SAK tools perform exceptionally well and it's usually the small phillips on my sak that I look for rather than hunt for one in my shop, when I'm pulling my photon apart to replace batteries. And I always know right where it is. It's in my pocket.
And when I want to drill a hole in something, be it leather or wood or whatever, there's not a stockman made that can match the awl on a SAK pioneer. And I've opened a ton of tin cans while camping using my SAK. I'll take it over a GI canopener any day and I sure wouldn't throw a regular canopener in my pack just to open a can of sardines.
SAKs take and hold a great edge for whittling, are easy to sharpen, ahd have great geometry. I like stockmans and have a pile of them but I'll take a SAK any day over a stockman.
