My Mexican cane is straight and smooth, and cut in fairly short tubes so you waste very little! I’ve been using it for years.
I use exclusively the 10.5-11 diameter, but I do have a small amount of smaller 10-10.5 cane.
For English horn, I have 11.5-12 diameter.
For sale by the 1/4 pound.
Don’t see the size or option you want? Check out my pregouged cane – I have some options (9.5-10!) there that don’t exist in tube form – and you save yourself all of that splitting, sorting, guillotining, and pre-gouging…
