I think he meant the 10" is smaller so less diamonds/core but why is the 18" so much more. The 18" has about twice the rim but core is about 70 percent larger and much thicker. They claim their prices are based on their cost from the Koreans but I remember when the new Korean 301 blades replaced the red notched rim made in CA blades. The 301 existing prices carried over to the penny. I'm guessing it is like gas prices. They charge what the buyers will pay. They are about the only manufacturer that has winter and other sales. They are having a spring sale on most of their saws now but not blades as blade sales have been strong.

plus there may be dedicated machinery for the very commonly sold 10" but the 18" has a lot less volume so amortizing setup and cleanup into a run raises the cost.

Most likely though the answer is simply "because they can".

"The 18" has about twice the rim but core is about 70 percent larger and much thicker."

The surface area of an 18” blade is three and a quarter times larger than that of a 10” blade.

!0” BD301 is 0.040” thick.
18” BD301 is 0.085” thick.

Assuming uniform thickness, the 18” blade contains almost

7 times more steel

than the 10”.
6.885 to be precise. ;D

Consider the Earth’s history as the old measure of the English yard,
the distance from the King’s nose to the tip of his outstretched hand.
One stroke of a nail file on his middle finger
erases human history.

Wrong. LOL. I knew better but it was just one of those things.

rocknrob: There was a shop in Portland, don't know if it's still there called Kenny and Zukes who made the absolute best pastrami sandwiches I have ever had. The problem is every restaurant thinks their sandwich is worth $20 now and seldom makes the grade. Nov 12, 2024 9:53:31 GMT -5

rocknrob: So, to end my thread on sandwiches. If you find your sandwich worthy of that price by all means keep going to that restaurant (chewie)
