[grussingcustomknives]

its better but i think this knife is ruined

 

[Matt Rochester]

Why is it ruined?

 

[grussingcustomknives]

To skinny at the tip

 

[grussingcustomknives]

Its thicker where the bump is

 

[Matt Rochester]

Well, knock it back.

 

[grussingcustomknives]

What do u mean

 

[grussingcustomknives]

This is really annoying all my grinds are like tjis[emoji30]

 

[Matt Rochester]

With that style knife the tip will be thin. If it's not then the edge isn't thin either.

 

[grussingcustomknives]

Ik but how do i fix it

 

[Matt Rochester]

If it's a Wharncliffe then it's going to have a thin tip. If you don't want a thin tip then make a different type knife like a spear/drop point. Anybody else? Am I wrong? A thin tip is part of the geometry of that knife. You can't keep the tip thick and get the edge thin at the same time.

Im going free hand from know on but it's still like that

it's all about pressure and the amount of time you spend at each part of the blade. you need to drag the tip ALL the way across the belt. if that makes the grind at the tip go farther up than you want use less pressure as the tip comes across.

But the part towards the handle is too low

I've found that I need to subtly rotate the blade as I get towards the tip to get the thinness at the edge without taking the spine to nothing as well. And I have to do that primarily with pressure towards the edge so it blends without creating another bevel. With a Wharncliffe or a Sandoku like is mentioned above lend themselves to thin tips.

Watch the video of me grinding

But the part towards the handle is too low

Then spend more time there

Wear some gloves perhaps during the initial grinding so you are not distracted by the sparks and heat.

 

[grussingcustomknives]

What type of gloves

 

[Maelstrom78]

I burn through the pointer fingers so I treat myself to a new pair every 4 knives or so.

These are thin enough for me to have good feel as well.

They sell this style everywhere in brick and mortar stores too.

Metal working is not something that comes to you over night. Sometimes there are things that you are going to have to put time in and find out what works for you. What works for one person might not for another. I just started grinding knives as well. I started by grinding metal scrap instead of my shaped knife blanks....
