The Infinity Knife
disposable blades keeps your focus on music making from knife grinding


"The new “Infinity Knife” designed by Mingjia Liu is a wonderful addition to

the marketplace.

One of the most important rules that I say to my students is that your knife

must always be the sharpest that it can be. Surgically sharp! That way you

can control, with exact precision, where and how much to take from your

reed. Particularly in the refining stages.

The infinity knife gives me the ability to get a keen edge by using my steel

rod without much fuss. It stays true, and when an edge is no longer

attainable, you can just insert a new blade without breaking the bank. Think

of that! With the escalating cost of knives, this one is a no-brainer.

I urge all players to consider adding this wonderful knife into their life - you

won’t regret it."
