When i had my woodlore i noticed that after serious batoning i had almost always lost its edge. Still sharp but not shaving. Yesturday i took a real dense piece of birch, batoned all the way through and i could still shave. Now i know these are not strictly scientifically accurate conditions, but i have noticed it on a number of occasions.
Im talking wood. It takes less effort (IMO IIRC!) to *push cut* through wood. ie feathersticks. The problem i had was i either went too deep with the feather sticks or too shallow, something which the Woodlore is better at for some reason.
Obviously the NS isn't better at cutting everything and in every condition as i haven't tried it in every condition i tried the woodlore in. For instance, i found the woodlore easier to carve delicate objects than i do the NS.
There is one thing though. When i lost my woodlore i wasn't properly finishing off a blade, there was not much stropping or fine sharpening. This may have left me with a sharp knife but a weaker edge. This may also have something to do with it (i just realised).
