From my limited experience this steel deforms (bends) quite easily. You may be able to straighten that blade tip back close to the original shape with just your hands and a vise. I'd use a vise with the jaws covered in some thick felt tape or paper to not scratch/dent, insert that tip in there (one bend at a time) and carefully straighthen by pushing the rest of the blade/the SAK in the opposite direction, then insert the tip into the vice a bit more, repeat, etc, until it gets as straight as possible. If you will do this be very careful not too apply too much force not to bend it worse than it is. Start just with a tiny push, then check, repeat adjusting with a tiny bit greater force if needed.
Somebody else may have a better advice than this.
In any case, good luck!
