ALL saws in this price range require sharpening and tuning. Hand sharpening and tuning any tool is a labor-intensive / skilled job; ...or the manufacturer must finance expensive machines to do the sharpening. Either way, most nice-cutting saws are expensive. The only exception to this rule is the Japanese style-pull saws which use machines to sharpen the teeth to tight tolerances, (less than .001") and then they use induction hardening to help teeth stay sharp. The reason these saws have come down in price is volume. Since the Japanese sold / leased some of their machines to Taiwan, the technology has been more available for competition. Now you can buy a decent Japanese style hand saw (like the Irwins or Z-Saws) in home-centers and countless online retailers for around twenty bucks... even less during sales. The only problem is that induction-hardened saw-teeth cannot be re-sharpened. Manufacturers know this, so they expect to make more profit from selling more "disposable" saws.
Traditional saws are another matter. They are intentionally made with softer steel so they can be re-sharpened. Manufacturers assume that any knowledgeable user understands this and has the tools and skills to sharpen his saws. So they offer discount saws that have the same intrinsic quality and are capable of very fine work. They just won't do it out-of-the-box. They expect the user to do the labor.
An important point here: There is VERY LITTLE difference between a ten dollar saw and a two-hundred-dollar saw except for cosmetic details ( fit and finish). The fancy boutique saws have good polished metal, ( instead of cheap shim-stock) nicely shaped wooden handles, (instead of plastic), machined brass backs, (instead of cheap folded steel, aluminum.) But even those details have less impact on the price than the labor and tooling that goes into sharpening the saw. That is why some makers can get one-hundred or more dollars for a little dovetail saw.
In this case, the maker, (Two Cherries) is a respected brand, but they are out-sourcing the saw manufacturing to someone else with too little oversight. So, you are getting good steel and a decent design, just none of the hand-work. It will cut dovetails and other joints as well as ANY saw, but only IF you understand how to tune it or are willing to pay an expert professional sharpener. (They are hard to find these days!) You stand a MUCH better chance of getting a good sharpening service if you learn to do it yourself. It doesn't take great investment in tools or time to learn saw-sharpening.
I mean no insult to the other disappointed reviewer. There is so much snake-oil being sold in the tool business today it's easy to get confused or to expect too much from manufacturers. The fact is, every experienced craftsman EXPECTS to sharpen his saws when they are new, ( as well as all of his planes, chisels or other tools.) It is ONLY because so many people are not knowledgeable that so many saw makers can get away with such incredibly inflated prices. When you see a saw like this for such a low price, you automatically KNOW it will require tune-up. If you don't know how to do that, then get a different style of saw or get your wallet ready for a cleaning. Premium saws now routinely cost one-fifty or more!
Of course the greatest cause of inflation is the fractional lending system and the Federal Reserve, but as consumers we must take some of the blame too. When we expect too much for too little, it opens the doors for inferior products. When we pay too much, because of ignorance or laziness, we drive prices up disproportionately to our already inflated currency. There will always be tool makers (and manufacturers of every kind) that take advantage of consumer ignorance.
I promise you, ANY knowledgeable craftsman can take this saw out of the box and have it cutting like a champion in twenty minutes or less. This saw is a great bargain IF and ONLY IF you understand all of this and know how to sharpen. Otherwise, you will be disappointed like the unhappy consumer was.
