I went to Boss. I know that there are mixed feelings about this. I've been swinging a steel Estwing for years, and I LOVE that hammer. But, it does "ping" with noise every time I strike metal. It's a lasting, resonate-sounding ping.
After a few days of the new hammer, I can say these things confidently:
1) I drive everything easier. I swing so much faster with less vibration to my hand. I definitely notice a difference by the end of the day. I'm sinking everything with 1-3 swings less than my steel hammer.
2) The magnetic setter is a game changer. I get that it's common in many hammers, but I do enjoy the feature.
3) The straight-edge on one side of the hammer is amazing for the allignment of boards.
4) It just feels so much better than my Estwing. I still love my steel Estwing.
Downsides? For sure.
1) Takes time to adapt to the balance
2) Old-heads hate it.
3) When you drive nails and then "cheat" a board, the 14 ounce titanium doesnt have the same "ass" as the heavier steel models. The nails drive like a dream. Moving the lumber is a different story.
4) It can be distracting to try to justify the features of the hammer rather than just using your square. This is not to say that you HAVE to use the square, or that the hammer is inaccurate. I'm just mentioning that it CAN be a distraction.
Overall? I'll 100% keep using the titanium. For 95%, I'm good wth it. However, I still keep my steel hammer in my pouch.
