I received these tips just yesterday (December 16, 2020) and was collecting Christmas gifts for my family. Please do not buy these knives (very dangerous) and I almost cut myself and I should sue this company for trying to sell a dangerous product when they should know it is defective. Now I feel bad because I can't finish the homemade crafts for my family in time for Christmas. If I could I would give minus stars. Now he messed up the router I bought and they have to pay for it and buy me a new one.
