I've been distracted with a Basque makila- inspired spear stick, since I came across some coyote scat in the back yard, which is my excuse for not being further along with this.
I snipped the pin in the donor knife by slipping in a knife and squeezing it in a vice. Don't try this at home! Always wear safety glasses! I also stood in a forward tiger stance to protect my cruxial vitals, tucked in my chin to protect my throat, and threw a rag over the top to retard the flight of anything that might have gone ping-sproing.
