some people love their multitools; I've had three over my career, and two have since been lost or discarded. personally, I don't see the attracting of carrying one; the 3rd ones stays in my duty belt, and I can't think of the last time I actually pulled it out, let alone used it.
If you want to spend the money on one, go nuts. it's your money
Carried a wave for years on my belt, but with raptors plus a knife I had essentially stopped using it. I kept leaving at the station and didn't have it for mountain bike rides where I actually used it, so now it lives in my sick red mountain bike fanny pack.
