There is always some risk involved if you intend to (ab)use an out of production blade that tends to sell for 2-3x (or more

) the original retail price due to rarity and a lower volume in circulation. As much as it sucks when one breaks, the manufacturer can't be held liable for the secondary market price of the knife. It's a risk you take when beating on unreplaceable out of production knives that should be taken into consideration. That being said, one of my favorite blades is a really rare model of vintage SHBM that, if it did ever break, would be devastating, because not only did I pay multiple times more than the original retail value, that even if I did get what I paid for it, there would be no way to replace it. It's a risk you take to enjoy the blades that made Jerry's reputation what it is. And to me, that risk is worth the reward. It's up to you to decide if you're willing to eat the loss on the off chance you do break a vintage blade.
