A handmade screwdriver has been on my mind as a possible purchase for a considerable amount of time now. I was shown this model by some cabinet furniture assemblers who work in the furniture industry. They have been using this model for more than 2 years virtually every day to assemble furniture, and they have said that it is quite powerful, that it holds the charge well, and that it has worked well for them. After that, I made the decision to buy this model, and I do not have the slightest regret about it. The only drawback is that it is not nearly as useful for completing activities around the house. It is applicable to work of a professional kind.
