I'm wanting to put together some kind of traditional styled slipjoint.

I have a piece of steel i want to use for it, and ive been trying to find sources for the normal sizes for the blades of different patterns to decide what to use.

Specifically the height. Ive looked at the chris crawford page, and that has the lengths but not the blade height.

If anyone has any experience with these. Or a source for info it would be appreciated.
 
Blade height varies. Draw out your plan on thin wood or aluminum and cut it out. Shape it to the final shape. Does it look good? If you like it, make the knife to fit it. If it is too tall or long, make changes in the cheap materials until you have a prototype you like. Use that to shape your final blade.
 
Some resources that might help are scans from old catalogs that have full size drawings. There is also a great web page that is an online viewer of "Smith's Key" which has drawings of Sheffield knives full size.

I have pdf.s of 1884 Hibbards-Ulster catalog, and 1920 Winchester shop notes document. The Winchester one includes detailed dimensions.

message me at my instagram ashwinearl ashwinearl , or PM here and I can email you the Ulster and Winchester catalog.

There is a knifemaker that sells bound copy of Remington catalog which also has full size drawings of knives. You can't see the tang, spring, but you can see the actual size and design. I don't have his name in front of me, but one of my knifemaker friends has one.

Hope that helps.

Hi, another suggestion is to buy an old one or new cheaper one (Rough Rider) take it apart and use it as your starting template. I find this very helpful to get started.

flea markets, antique stores, ebay, garage sales are good for these. Though the Rough Rider's I've seen taken apart are very nice for patterns with half stops, as many old knives have rounded tangs.

Another source for old knives some very expensive, some dirt cheap is PLEASE - NO SALES LINKS - Moderator.

Print the picture up. Measure the length. of the blade, on the page and print it up again but adjust the percentage up or down to get the length you want, and click the box "preserve the ratio"

When you figure out the percentage to increase or decrease the blade length, height will be where it is suppose to be.
 
Since you know the length, you can measure the height. Just resize the image on your screen to 1:1 scale. Either that or measure the length in pixels, divide by the actual length in mm, cm or inches.

Example: 1442 pixels long blade, divide by 12,5cm = 115,36 pixels. That's your scale.
Then measure height of blade = 351 pixels, divide by 115,36 = 3,04 cm.

Works on any straight, side-on shot, as long as the parallax error isn't too extreme. Just remember to rotate the image to line the object up horizontally if its not already.
 
My apologies.
I just realized you are in Europe, where they use the decimal comma instead of the point.
Your 115,36 is my 115.36

When I was around 7 or 8, I visited a physicist colleague of my grandfather's who wrote a number like 123,345,67 - I waited for him to write the last digit. I asked him about it and he said he was from Poland where that is how they write numbers.
