When playing untwinked, you will probably need that polearm before you finish the Larzuk quest which grants 1-2 sockets on magical items... and there are surely better things to do with it than that.
Items with the savage affix have a level req of at least 19. IMO Dimoak's Hew is better (level req 8, 100%ed, 20% IAS, its -def is next to irrelevant) and good enough until your merc can wear an Insight weapon, but it might be a bit hard to find when playing untwinked.
The chipped gem recipe can probably produce better weapons... and they will have 1-2 sockets on top of its affixes.
Yes, in 1.09 it only worked with swords, but you got 3 sockets instead of 1-2.
I never got a CCBoQ with the chipped gem recipe, just a plain cruel one... but I stumbled over a CCBoQ in Larzuk's inventory while looking for echoing axes, with more than 290%ed. That bastard added just one socket, but it still rocked on my WW barb!
