almost there, it's spelled ekki but is also known as azobe.

often called red ironwood and i can understand why a normal blade will be dull in seconds. turning it is a a real challenge as you are sharpening you're tools every few cuts.

 

it doesn't surprise me that a tct blade wont go through nails as you can cut iron on a table saw... it shatters teeth, i lost a couple when i hit my thin steel rule with it so a nail is going to remove lots.

Yes that's the one, thanks for the clarification

I guess he doesn't come across that many nails.

I was talking to a firm who supply the mentioned chains to someone who cuts railway sleepers,he can cut 8-10 of them before they need sharpening,on standard chain he could only manage a couple,the ones he used were made by oregon,he rated them alot.

 

I bought a saw off a guy in San Antonio, Texas a few years back that used carbide chipper chain to cut railroad ties with. He said they lasted quite a bit longer between sharpening. He showed me some of their work saws, and the amount of tar and creosote and gunk on them was stunning.
