This question seems only accidentally related to gardening. In general, I would imagine tool and tool repair questions would be better asked at the Home Improvement site.
There are tool-related questions that would be better asked here, such as whether one tool or another are better for some gardening task or questions in which the gardening aspect of the question is the most important aspect of the question.
Or am I being too picky?
(The distinction between this question and this one is that I think the question would be fine except that the Home Improvement site exists and might give better answers.)
