A rumor I heard during my internship where I ran MIL-S-901D experiments was that the government spec'd a very specific type of hammer from a supplier to perform this test. The supplier went out of business, but the spec still required the old hammer. So the cost for just hitting an object with a hammer jumped to $4k+ since there were so few compliant hammers on the market.
