I'm having trouble viewing the link above , but i think it is a problem at my end .
I have owned Grafting and Budding knives for years , I was an orchardist ( apples and pears ), and that is where I first started buying Tina knives .
The one pictured with the strange bump on the blade we used for Budding and Grafting and the more plain sheeps foot type blades were used for Grafting only .
After I gave up growing fruit I continued to carry my Tina 605 ( sheeps foot blade ) as an EDC because they are a fantastic knife .
