Have a picture?
Have you used one much before? Ive had newer and older knives, I found I liked the older ones better, and they usually can be bought for less money.
I was having a heck of a time getting my knives truly sharp when building cabins. A cabin builder neighbor stopped by once when I was building one, and dealing with the drudgery of trying to tune up the edge on a knife. I asked how he sharpened his knives, he said "Show me how youre using it", I did, flat side down...he said "turn it over, use the bevel side down, like a chisel". Once I worked the concave-ness out of the flat side and only used it bevel side down it became hugely easier to sharpen and keep sharp. What was previously an hours toil to get truly sharp became a 5 minute simple job, and I could keep them shaving sharp with a two sided round stone and spit.
I loaned knives to a couple people with the stern admonition that they HAVE to use them bevel side down, or dont take it. I could instantly tell when they didnt listen, which was every time, by the wear on the flat of the blade. No more loaning of drawknives.
Some new knives ive seen in stores had a secondary bevel ground on the flat side, it would take a LOT of work to remove that and get it right and easy to correctly sharpen.
One well known cabin builder showed pictures in his book using his knife flat side down, then mentioned that sharpening one was a job for a pro, its too hard to get them very sharp yourself. Using the bevel side down would change that.
If you dont have a blade guard, a piece of 3/4" pvc pipe with a lengthwise cut on a table saw makes a good guard. It snaps on friction snug.
