Ditto- material is removed but we try to keep the V's as narrow as possible with two man, simply to minimize ax blows. this becomes increasingly difficult with the increase in required depth, the score notches grow as you approach the buttress and at some point our V's change to W's so that a chip is ejected with every blow.
This leaves a very distinct blem with over- penetration and I wish to explore frames in geo-locals where two man was practiced with the added interest of finding such a blem.

The distance betwixt notches is maximized and varies from stem to stem after gaging splitibility of the juggles, looking for, say 3 blows max to split off a juggle.

We rough hew with a felling axe after juggling to within that 1/8th and likewise "backscore" trying to barely penetrate the anticipated finished face. It is only at this point that I pick up the broad ax
