That's what the chain brake is for. But if you really swing that puppy hard at your leg you just might cut it off with a stationary chain
I drop start all the time - remember when chainsaw manuals outline safety tips they have to cater for the most accident prone, dumbest, most inbred, mentally handicapped people on earth and does not mean it should be taken as safety gospel. Those that do believe those precautions should be adhered to 100% may just fit into the above outlined category
In fact the only saw I won't drop start when cold is my 5100-S. That thing has that much compression it's a pig and my size 13 boot won't fit through the rear handle easily I drop start all my saws when they're warm, even the 3120 which is actually the easiest saw to start in my whole stable, hot or cold.
This. There is a chain brake you guys know....
