Yeah Swataramike, I’m one of those guys who can’t ship till April. We still are hitting the teens at night and getting a bit of snow. I only use obsidian and it usually seems more brittle in the cold so I wait till we’re staying above freezing for a couple days. Also it’s just too darn cold for the fingers when it’s so chilly! I broke an arrowhead into my pinky a while back and cut through the tendon sheath(thankfully not the tendon) and didn’t feel it for a couple hours waiting in the ER my fingers were so cold. Think it was -10 or something when I did that.
