The files should work for (wait for it......) filing. If not cold filing, then hot filing, or if totally shot, use the hi carbon in projects.(See TP's comment above). The rifflers (bent files/rasps are good in the woodworking toolbox for sculpting. Chisels are great for their intended purpose, and also can be adapted by grinding or forging into more chisels, punches, drifts, fullers, etc.The flatbar would end up as intended in my kit, unless I already had a bunch, then...... Not a bad haul. I tend to have a few buckets of imilar material waiting at the ready.
