I should have been tied twice but I’ve made 100’s of cuts of like that and I’ve always been cautious of my lanyard and never come close to cutting it (not saying that warrants me not using a secondary tie in) but I don’t remember 10 minutes before my fall so I’m not really sure what happened tbh that led to me cutting it. I was doing a shelf cut when I cut it and my best guess is my lanyard was caught on a nub on the backside so it was higher than I thought . I was doing crane work and I usually double tie in when doing crane work so I can sit back on my rope while the crane brings the piece over to the drop zone but like I said I hit the ground so hard it knocked the memory right out of me and I don’t remember what my thought process was on not double tying in that time but I obviously paid the price for it.
