Preshaped gravers are great, and I recommend them to all people learning. However, I’ve found the combination of the Komet Maximum wheel and the Edenta Ceragloss to be a super quick and economical way for me to shape and sharpen any graver I need, whether from a blank or an old bur.
It’s a steep learning curve but an invaluable skill that’s absolutely worth having. I found that when using the nicely reshaped gravers, I was more hesitant to modify them for specific cuts, not wanting to ‘mess them up’. But with these, I don’t mind creating a graver for one specific cut on a job if it’s needed to get the results that I want.
As my skills grew in the beginning and the complexity of the jobs I worked on increased, I found more and more instances where custom gravers became a necessity. Now, even making simple 60 V gravers is just easier this way for me.
