Blank extension tool

Great tool I did not know I really needed it until I used it just One time .Now it will be part of my rod building Arsenal .

Could be better

This isn’t a bad tool, however if it was in stock I would have gone with the CRB Pro aluminum set, however I needed it at the time. That said this being plastic, it flexes then backs out of the blank causing you to reset it frequently. It works as needed but if you have the extra $$ and Mudhole has it in stock buy the set

Has worked out great for wrapping and drying

Kenneth Stabler (Philadelphia, PA, US)
They work ok

They do the job but not as nice as the crb pro aluminum ones

Great tool

I use this tool a lot when making fly rods and while the blanks slip off even when I put tape on the extension tool, it does help. I have been temped to put something on this like rubber cement or double sided tape to help with the blank from slipping off but I am worried it would gum up the inside of the ferrule. That being said my old rod wrapper came with wooden extensions and I had the same issues with those as well. I wish these had some kind of rubber sleeve or replacement rubber sleeves to help grip the blank.
