I had to get this for a retaining wall I am buildingout of railroad ties. Its a Bosch Wormdrive saw and a prazi Beam cutter. I wanted to test it out so I grabbed a 6x6 and made my first cut it cuts great till you hit the hidden screw that was in the wood. now it will not cut for crap. Oh well I will sharpen it and and get a new chain and be more careful next time.
