Lin, the drawknives on the rack have the flat side to the rack. Bevel side is the side you see.
The handles are bent towards the rack also. The best way to understand how the slight bend in the handles work is this way.
Stand with your arms at your sides but bent at the elbow 90 degrees. ( like you'd hold a bag of grocerys) Now make a fist like you were holding a drawkife in your hands. The most comfortable position would point your edge at your toes not your belly button.
You get the most power in your shoulders and biceps in this way but its hard on your wrists to cant them to flatten the blade to cut with.
With the slightly bent handles you can stand straight and not bend over to run your drawknife. Lots easyer on the back and wrists. Hope I didn't confuse things more
Next day I'm here and not hunting I'll get a picture showing the handles in relation to the flat back of the blade.
