i have my great grandmother's pinking shears- she passed away 60 some years ago- she passed them on to my grandma, who gave them to me- i have had them sharpened twice in the 30 years i've had them- i love those shears! find a good reputable person- who specializes in them- not everyone who sharpens shears has experience with pinking shears- and the wrong person can ruin them- the right person however can make them good and sharp for many years
