Why should you go cut when you can go blunt, knockdown and same speed range for a little extra gold?
By the shape hafted blade (Not the longer version) wouldn't be bad as a bonus to shields weapon since the only 2 axes polearm has available cheap are very slow... say something like this would be better imo:
Hafted Blade
weight 3
requirement 10
spd rtng 94
weapon length 132
swing damage 36, cut
thrust damage 20 pierce
Penalty with Shield
Bonus against shield
(Don't forget polearms get -22 range from grip so it won't be that long)
