It seems to me this issue is related directly to big box stores. I used to use Klein professionally every day, but my stuff is/was all pre-big box stores. The tips have lasted very well. The last Klein purchase I made was in about 2003 or so. All my stuff has the rubber handles without the raised lettering. Right after I finished buying my Klein tools I started seeing their brand moved heavily into big box stores, and I soon after started hearing about quality going down. Now I see threads on Garagejournal about the big box stores dropping pro brands and going to house tool brands (and dropping Klein) and all of the sudden Klein is announcing a higher quality tool again. Coincidence?
I personally like seeing the established and good quality professional grade tools only sold outside of places like Home Depot, etc. Every pro brand I have seen go into the general consumer market has had to drop the quality in some way over time to stay price competitive, because all the average consumer really cares about is price. Ridgid has probably done the best (in my opinion) at staying true to quality while being sold in big box stores (with their hand tool line), but I have noticed that even they have been recently cutting corners to most likely meet price points. I have noticed that in the last few years they have stopped grinding down the metal seam that runs down the pipe wench handles before painting them. I have purchased a couple pipe wrenches in the last few years and the first thing I have to do is grind off the seam so it is smooth and comfortable in my hands like all their older pipe wrenches are. Channellock seems to be letting quality control slip a bit as well, and I wonder if it is because of the increased production demand and price controls that distributing to home centers creates.
It might make it harder to warranty, or harder to find and buy, but a truly good quality tool that is used properly should really never need to be warrantied. It just slowly wears out after many years of constant use, and then you buy a new one. The original tool gives such good service to the owner that the average person would feel ashamed to try and warranty it as if there were something wrong with it. Price will go up a little bit after the brand leaves home centers, but price is not as much of an issue to a professional user, because it is amortized out over hundreds of hours of constant use instead of the price having to be justified for occasional garage use only.
I like that Klein is making a better screwdriver again, because as soon as I started hearing about the quality issues when they were being sold in big box stores I started buying other brands instead, and most of the other good brands of screwdrivers are foreign. If the new screwdrivers are in fact well made again, I will buy from them again in the future. I always did like the extra thickness of the Klein rubber handle surrounds.
Is it a chisel?
