I am a long time grafter and my pick for a grafting knife has always been a Tina blade. In recent years I have found that the quality of the carbon steel has undergone some changes. One has to constantly sharpen and strop in order to keep a servicable edge on the blade. In searching for a better blade I was afforded the opportunity to use a blade made by Hershell. I am so impressed with the quality of the blade. I grafted over 150 liners and did not have to strop the blade one time. I will never own another Tina.
