if im gonna break it....i want to break it in my garage
i am very happy with its performance
i actually used a 2 lb. sledge
A SR77 knife should be plenty strong enough to hold up to beating with a hammer or sledge.
HOWEVER, hammers and sledges WILL start to deform, ding, mar and mushroom any steel over time.
SR-77 is based on S7 steel which is an impact steel used for jackhammers. Jackhammer bits will deform. So will SR-77 if you beat on it with a hammer.
Deformation is not solely based on a harder steel deforming a softer steel. They will deform each other. Softer will just deform more and faster.
Less tough knives than those from Scrap Yard can be broken or seriously damaged if batoned with a hammer.
A hammer, cold chisel, sledge, maul or wedge that you would hit with another sledge and other steel tools that are intended to be impacted onto other pieces of steel are typically not hardened to the level of most knives - to help prevent them from breaking and/or chips from flying off of them.
Same would be the case for a cold chisel or a jackhammer bit. They are not hardened quite as much as a knife needs to be to hold a good edge.
A wood chisel is hardened at the tip, but not so much at the handle.
However, a hammer or sledge does have the ability to put a large amount of "impact" force onto a small area. A hammer would actually be a little worse than a sledge with slightly smaller contact area. This high impact on a small area can break many other knives and can still deform your Scrap Yard knife.
If you learned the abilities, capabilities and faith in your SR-77 from testing it against a hammer, then maybe it was worth it to you.
*** The lack of damage to that knife having been beaten by a hammer should be VERY impressive!
But, batoning is typically done with a piece of wood. And now that you are satisfied with it's abilities, I personally highly recommend using pieces of scrap wood for batoning.
A Scrap Yard knife may be able to deal with hammer blows, but a piece of wood can deliver enough force to get the job done without doing as much damage to your knives.
A piece of wood can generate almost as much or possibly as much "force" depending on the size, shape and density of the wood, but wood is highly unlikely to deform your blades. Hammers will over time.
Batoning on "knives" is NOT intended to be done with other pieces of steel. I don't care what type of steel it is.
****** For the record, the larger Swamp Rat knives that are differentially heat treated are significantly softer on the spines. They would deform much more rapidly from impacts from a hammer or other piece of steel. They are plenty hard enough to handle a wood baton though.
