Well, how about carrying around the tool and having someone else do the work? I am available for most small to medium projects and handyman services. Extensive references available for a multitude of different trades. And, if it's not something I would take on, chances are I have a good reference for you. This tool was used for a day, so my price is fair and firm, but I do offer discounts for multiple items purchased, whether it's tools, furniture, antiques, vintage items, household, Christmas and Holiday decorations, or garden & landscape supplies, so be sure to check out my other items!
