Hi,

What is the intended purpose of breadknifing here?
I've heard of folks breadknifing on fine surfaces, such as
glass or the Shapton 16k, but if you are correcting a frown
or something like that then you need to remove more metal
with something like the D8C.

in short, yes you can.
Unless it is a serious frown or a large chip I avoid breadknifing and even in those circumstances. Instead, in the case of a frown or large chip I will either do a few layers of tape and flat hone or keep the spine off of the hone and work on it as if I was sharpening a knife. This way I'm maintaining some semblance of a bevel while I'm removing the intended portion of metal.
I've gone the breadknifing route for both a frown and a large chip and getting the bevel back is one heck of a lot of work IME. The less radical method mentioned above has been much better for me. In the case of micro chips breadknifing is serious overkill IMO. Flat honing will get them out and turns out to be way faster. Just my 2 bits.

You want to really really think, before Bread-knifing a razor, I am one of it's biggest proponents and I am telling you right now it is a ton of work and it is a Restoration technique it is not part of honing...
Post a pic of the blade edge...
While I was reading this:
Honing a damaged blade - Straight Razor Place Wiki
I realized I will eventually drop my straight or ding it on the tap or sink, so I am trying to prepare for that since I want to buy my honing equipment at once.
It recommends a 220 Norton or similar low grit stone. I was planning to get a DMT8C so I was wondering if that was suitable since it's 325 grit, then I could just get hones from 1K and higher. What do you guys think?
I read somewhere you can rip diamonds off the DMT8C, I don't know if this is just a myth but if it's not I don't understand what conditions it could happen under.
Thanks
That Wiki article is a condensed version of a thread I wrote awhile back, which gives the same warning as I just did...
Always follow the links back to the Original threads to read the asked and answered questions that the Wiki does not have... The threads have way more info...
Faucet dings are not bad enough for Bread-knifing a 1/8 chip would be more in line or a huge frown... or the dreaded "wowie" or double frown... In other words extreme stuff...
And YES the DMT 325 is a great plate for restoration and lapping other stones to answer your question....
ps: If anyone would rip diamonds off a dmt it would be me and I haven't managed it yet :)
When you get that DMT D8C get the continuous plate and when you lap your stones do it under running water in the kitchen sink and it will last for many years. Josh Earl has a tutorial with photos in the SRP Wiki called Hone Lapping 101 that illustrates and explains this.
Also, when you get your plate take a hunk of iron, a chisel if you have one, and go over the wet plate to knock down any high spots. Make sure to go over the edges and the corners. I don't have any chisels so I use the shank of a 12" Stanley screwdriver. It is called 'breaking in' the plate and is a good thing to do.
Diamonds are hard, but the nickel plating that holds the diamonds is not. Grit from the hone can undercut the nickel, causing release of the diamonds.
Two conditions can cause it to happen, especially in combination. The first is failing to use enough water to adequately wash the grit away. The second is lapping a hone with a grit that is larger than the grit of the diamond, resulting in the hone grit reaching past the diamonds and cutting into the nickel.
With any diamond implement lubrication is of the utmost importance. Back in my college days in the geology lab when I used to cut up rocks we had a 14 inch saw and we used a combination of motor oil and dieisel fuel to lube the blade.
