pinking shears are EXPENSIVE and will last generations (i still have my grandmother's and she has been gone for almost 20 years) they are made to last. they can be sharpened by a professional scissor sharpener- and will hold a good edge for a long time- well worth what it takes. i could not imagine even considering just (tossing them). since a good pair cost's $50+ if you can find them on sale. i will probably pass mine on to one of my granddaughter's some day
