I think the wrench is fine. Definitely looks better with the lightning bolt clenched in the fist. As others have mentioned, it looks like a good designer did the logo, and then the customer messed it up by trying to add something to it in MS Word.
Also, a phone number rarely has any place in a logo unless you're in the business of pizza delivery. It's a logo, not a business card.
There's a tiny hole-in-the-wall Italian market in my neighbourhood that I've been passing by for almost 5 years, thinking it was a takeout restaurant. Just the other day I figured it out, and it took me a second before I realised it was the fact that their sign out front says "Gourmet Pasta" with a phone number plastered all over. Somehow I had subconsciously ignored it for 5 years because there was a big phone number on their sign.
