Good read above
Component based in my reference is most older hammer designs were 4 or 5 body pieces that were stacked up and bolted together meaning every part of the body was individually replaceable for an inexpensive price compared to a new hammer body
The newer hammers of realy cheap manufacturing or geared specifically for the rental market are single piece bodys they are limited in rebuilding because it requires sleeves to be machined into the bore on most designs witch all included can get real close to new cost
I like npk for most of those reasons tho there new hammers in the small sizes are unibody and but there big ones aren't
Big things with hammers over say 2000lbs neess a dampener designed in npk did this with rubber and neoprene blocks between the body and holster cat hammers did it inside with a dapinig bladder on the piston it also cushions the hit most manufacturers did internal dampners to my knowledge
Cat hammers hit like a Lewis gun they are way fast npk is typically a 3rd slower in equal class but I have put npk hammers up against a cat hammer in the next class up and walked away from it cause while it hit fast and had about 9000lbs more machine backing it up it didn't hit hard
Another trend I have noticed lately is a lot cheap brand hammers are getting rated for x class and the hammer has physically half the weight of a reputable brand so it can go on a lighter machine so on paper its x size and in reality it's not cause the impact is only as good as the weight to hold it down
