I inherited three kenzans from an elderly aunt and I used the straightening tool on each. Now there are all aligned and I've been using these old kenzans to make new arrangements. It is a necessary tool that is worthwhile keeping in the tool pouch.This little tool is invaluable if you take Ikebana and use kenzans (pin holders). One end cleans between the teeth of the kenzan and the other end fits over the individual teeth to straighten them, as they often become bent. Very handy.Mother uses it for flower arrangements.perfect for the jobExactly what I thought it would be.good
