So far I always place the blade it the vice so that the flat part is parallel to the base. To find the sweet spot I move the blade forwards or backwards, keeping the flat part parallel. A lot of my knives have a small area of the spine at the heel that is square but then quickly tapers off. So if I need to slide the blade back in the vice to get the sweet spot I often run out of "square spine" area.

I have read about others who "tip" the blade down? (or up?) to achieve the sweet spot.

1. How do you do this? Any tips other than using the sharpie to check for the sweet spot.

2. Is there a formula? If I have the edge parallel and want to slide it back 1/2 " more, then instead how many degrees would I tip it down?


(Hey Mods: we need a section for setting the blade in the vice?)

Part way down the linked page, is a way to angle the blade by putting tape on a stone and marking where the edge is in the clamped area, then line up the knife tip to the mark on the tape by tilting the knife.

Thanks Mike. I remember seeing this now.

That raises another question. When you tilt the blade down how to you get it back in the vice exactly the same way next time? That is the easy part of mounting parallel is I can record the setting on the alignment guide (ruler) and put it back the same way.

With the blade tilted how to measure a. how far forward/backward it is and b. how much angle it is tilted?

When you use the tape to you get it perfect? I.e. the tip and the main flat section both touch the edge of the tape? Reason I ask is do the same tape trick with mounting parallel, but the tip never quit makes it to the tape. The end result is normally a pretty even bevel though.

Curtis had a very good idea about this a while back that we're working on: a transparent ruler that the depth key can plug into. This ruler would extend upwards, allowing you to align the edge of the blade with various vertical marks such that any tilt would be recordable and repeatable. No time frame yet on development, but I'll keep everyone posted as we progress.

I haven't used tape in that manner, but I'd guess I'd settle for close to the line. I use the sharpie. I'll compromise some inorder to clamp on a flat portion of the blade.

I would hazard a guess, that if you used the tape-to-stone trick each time, you would end up in ~the same position each time.

here is a solution from a while ago put up by Larry at SW Florida Holster that I really like for recording the tilt when you tip the knife so it isn't resting of both pins - or don't use the depth key at all. Use a drafting triangle in combo wiht the alignment guide. Triangle give you height and the alignment guide lets you record how far away from the vise you are measuring. I use this a lot on dagger style blades where I don't use the depth key. It can work for placing the knife flat (horizontal) or tipping. I record the tip height with distance forward and the blade height at the handle just as a double check to be sure I get it tipped the same amount and if it is horizontal I measure tip height and the blade height at the vise to get the same depth into the vise.

Thanks Bob,

Great idea. This should work and only need one hand.

Thanks Clay,

I have one of these.

Something like this might work. I long straight edge that mounts in the depth gage holes, with 1 or 2 legs that move to locate the tip. May or may not need the protractor part.

While we are on the subject if you ever re-do the alignment gage add more increments, i.e. quarter and eight inch marks. I have drawn in these myself.

I have found that if I am using an angle cube and know how to make the knife edge perpendicular to my edge then I don't really need to record the height of my tip. It is pretty simple to repeat it and the sharpie trick verifies this. ;)
