A few months back, my daughter caught her left forefinger on the blade of a stick blender. She underwent reconstructive surgery and has had lots of physio to get things back to normal. As she's left-handed, it's made life rather difficult for her.

You really need to be careful with stick blenders. Daughter has now thrown hers away.

Ouch! ((holding my finger imagining the pain)), that must have been extremely painful. I used to use a stick blender myself , but no longer have it.
How much of her finger did she lose or damage ?

She didn't (luckily) lose any of her finger, although it was a close run thing. It was the last two phalanxes that were damaged. I have no doubt that in time she will make a 100% recovery, but it is slow progress. She complains about strange feelings in her hand and a cold sensation when she uses the damaged finger.
