This thread got me thinking so I decided to calculate the grind angle on some of my knives using the following method, two measurements, the thickness of the steel and the width of the grind (assuming a flat grind) and the following calculation
I have a knife to the same design and spec, or very close to it, as the AW/Ray Mears one. Blade thickness 4.05mm grind width 8.5mm this gives an angle of 27.56 degrees.
Next my mora frost clipper. Blade thickness 2 mm grind width 5.44 mm this gives an angle of 21.18 degrees.
Next a frost short blade sloyd, blade thickness 2.65 grind width 6.39 this gives an angle of 23.93 degrees.
Lastly a frost sloyd with the longer blade, blade thickness 2.7 mm grind width 5.59 mm this gives an angle of 27.95 degrees.
PLease note the blade thickness did vary very slightly along the length as did the grind width so I had to take an approximate average to give a reasonably accurate estimation, also I have hand sharpened all of them using a wet stone several times and am no expert at this so I may have changed the angles a little from new ?
I was surprised as the two frost sloyds feel much more "delicate" probably because of the shallow and thin blades tapering to a point.
The mora clipper is light and comfy to use but without measuring I would have said the angle was bigger than the other frosts.
The hand made bushcraft knife is much heavier, thicker blade but does feel comfy in the hand but does not feel that it could do delicate carving as well as the two frost sloyds.
I would say that any hand made knife to similar spec to the AW/RM one would be just as able to do any job the percieved more prestigeous one could.
However, compared to the others it feels clumsy if you wanted to do some fine carving type of work.
