Perfect on cold hard butter, so it will be soft to spread on bread and biscuits.

I HAVE BEEN WAITING AND SHOPPING FOR THIS TYPE OF COLD 'BUTTER SPREADER KNIFE' FOR YEARS, WITH ZERO SUCCESS. I NOW HAVE YOUR BUTTER SPREADER KNIFE, AND THIS UTENSIL IS EXACTLY WHAT I HAVE BEEN 'HUNTING' FOR IN STORES, AND CATALOGUES. THE KNIFE'S SIZE, WEIGHT, AND THE 'TOOTHED' SPREADERS, ARE HIGHLY FUNCTIONAL. THANK YOU!!

Love it. 😊

Used it for the first time today. Does exactly what it is intended for. Good little tool.
