Have to adjust for each size which is a pain !!
And that is the beauty of mine, Mart, it is self adjusting. You can put a black walnut in the bottom jaw "cup" n' crack it, followed by a hazelnut, then a hickory nut, etc., etc. ... and just keep right on a "levering" back n' forth ..... and you get a perfect "crack" most every time.
And Mart, that was really nice of you to offer to send me some pecans because I love the taste of them also. I luv the taste of all the native nut species; Black Walnut, Butternut or White Walnut, Hickory nuts and Hazelnuts.
But Mart, I'm not able to crack them out and I know Violet would not be thrilled about doing it. .... And they always tastes better when ya crack them for yourself.
Mart, I ought to sell you that nutcracker because I haven't used it in the past 10 years or so and have no plans to do so in the future.
And I thank you again for the offer.
