I can’t make a closed fist anymore which has forced me to use bas rutten open palm self defense strikes when things go sour in the streetz.

I’m proud of what they have become, gnarled claws from 10 years of choking and gripping and grasping. Here’s to the next decade of mangled digits. Photo by @stefankocev
