Strength build, skill and side weapon advice

Hi there, im new to bloodborne and about to finish my first playthrough. I didnt test many weapons because i really like the wirhligig saw. So i chose to build around it, here are my stats: SL80 VIT40 END25 STR35 and nothing else touched except 1 or 2 points in arcane and bloodtinge.

Now my question: I want a useful LEFT HAND weapon and skill advice, i just dont want to lvl past 120. Pls help me out
