Eeks, that is a bit pricey, but then so are blades!

Thanks for the review on the sharpener... I like the idea of just having to push the button........ as I am no longer into the physical
work out idea. I am at that age when over working a part of the old body can cause issues...... pains and aches. And that presents problems with sewing. I will look into it and hope to find one on sale. Thanks again.
