As far as the HF saw goes, it is probably fine for a few cuts a year. The point is that if all you have ever flown is a Sopwith Camel, you cant comment on a P-51 Mustang with a Rolls Royce Merlin mill, and you will be happy as a clam with your Camel.
If you have never cut wit a Forrest blade, then a Harbor freight blade can wood butcher with the best of them for a few cuts, of course you could use a chain saw and a file and get a miter pretty close in a few hours.
The basic fact that most people do not seem to be able to grasp is that value is computed by cost divided by the number of times you can use that which you have purchased.
A good example is a carbide bit for a hammer drill. Say you have to drill thousands of holes in concrete. To get value you have to divide the cost of the bit by the number of holes you can drill with the bit. It comes down to cost per hole, or with a saw blade, cost per cut.
The point I am trying to make is that carbide saw blades are expensive. If you buy one that costs twice what the average blade costs but lasts ten times as long you are a smart feller, as opposed to being a fart smeller.
idk what you mean by "a few cuts a year". but i have many 100's of cuts on mine. and like i said, it makes clean cuts with no issues. i don't use it for trim, but why would i, its not made to make cuts THAT clean.
I have made trim cuts on my older 10" saw which I am selling. I never had an issue with that saw and I have had it for 2 years now. Only reason I got the 12" is for the dual bevel it has. The stock blade cuts good for a 60T HF brand blade but I want a blade that makes even cleaner cuts and will last longer.
