Part 4/7:
In addition to firearms, I examined various metal samples, including some that showed unusual characteristics. For example, I came across a large, bent wrench with an atypical shape—it seemed as if some force or process caused it to bend or "heal" in a strange way. I recall my prior collection of metal samples, many of which have been sold or given away; the majority are now gone, but a few remnants still remain.
One particularly peculiar sample was a heavy, classical wrench with a healed or healed-like appearance, which could suggest crystallization or metal jellification—phenomena that can occur over time due to environmental factors. I tend to keep these samples preserved carefully, often in special containers, to observe how metals react over long periods.
