What Knife do you use for Castration?

Well of course ANY procedure needs to be done correctly...
 
Howdy guys. Can't speak much to sheep and pigs but can tell ya bout cattle and horses. As far as the knives go really just bout anything will work. You'll see some differences regionally probably more than anything else. In cowboy vernacular a knife for castration is referred to as a "nutter". For GmpaJim GmpaJim and others I'll try and keep it relatively clean.

In our area and many places the knife of choice is a Case Trapper or something similar. Can't say I've ever seen a Stockman used and seldom the Spey blade on the trapper. Mostly the pointy one. My small fixed blades are very popular too and I would say most of my customers are working cowboys rancher types. Here the wife and I were helping the neighbors:

This young man was using the spey blade and honestly thats the first and only time I've ever seen that:

And this one too:


I do make a Castrator as I call it. I don't make a lot of these as its just a different tradition around here but they sell other places. Here's a thread on its development and some of the regional differences and the why:


I once had a very experienced cowboy from our tradition draw out the perfect branding knife (a branding is where the castration is done). I'd asked him in his 40 years of being a big outfit bedroll cowboy how many calves he'd cut. Ya could see the math going on in his head and he said bout a million. This is what he designed for me. I've made and sold many hundreds of these:

Heck of a Bird and Trout too. Anyhoo, as far as technique goes, there's lots of different ways of cutting a calf its just not slash em off. A few folks had mentioned rubber bands and we did, some years back, experiment with banding. It's not as effective and we felt it was more painful and bothered the calves more. Banding takes a couple of months. Unless a ranch is raising bulls to sell to other ranchers all bull calves are cut and then they are steers. My wife does most of the cutting on our outfit and she had me design and make her a special one off castrator. Basically took one of my paring knife designs and rounded the front tip off:

She carries it in a boot sheath while branding:

Handy that way when needed. Remember approx half your calves are gonna be heifers and won't need cutting:

A disinfectant spray is used afterwards and the knife is rinsed and dried in between calves:

Using her regular EDC here for some reason:

A young lady 17 at the time, had been helping us for some time and she wanted to learn how to cut a calf. So my son and a friend Cody (whom between em have probably cut a quarter of a bilzillion calves) were talking her through it. After she made the first slice she asked what she did with the knife till it was needed again. They told her to put it in her teeth and she did without hesitation (keeps it out of the guacamole). Not squeamish at all.

Horsewright took me back 40 years. Just as I remember it. Some blade of yours, any blade, is on my 'will buy' list.
 
When we band a young lamb, he will squirm for a minute or so and then act normally. The balls fall off in a week or so. The one time that we banded an adult ram, he ran around and rolled on the ground for a few minutes. I think he was uncomfortable for a few hours, but it's hard to tell with prey species. The next day he was back to normal except that he would not come near me for a couple years--I held him while the vet put on the band.
 
Id say whatever knife you pick just make sure it’s sharp. Wouldn’t want my balls cut off, but I think I would prefer a sharp blade to a dull one if I had to do it.
 
Always appreciate Horsewright's insights and illustrative posts about his talents, work and lifestyle. I want to be him when when I grow up!
 
Horsewright Horsewright As always, great photos with wonderful knives. Living a great life, it seems.

To the general thread topic, very interesting observation that the boy there using his Spey blade to... spay, is the first time you've noticed someone using one for that, despite that being supposedly the whole reason the shape exists, makes me wonder... I bet if asked, his answer would be for the reason that it is a Spey blade. None of the older men using folders are using that, and the man who castrated a million steer's preferred knife certainly did not look similarly.

People accuse certain parts of the knife industry of solving problems that don't exist or exaggerating need, that are created so t can sell more knives, specifically in the "tactical" genre. While some are insanely ridiculous (A knife the shape of Israel that has a hole in it that is a "rangefinder for TOW missiles) and some are actually useful (the wave feature making the draw on some folders equivalent to drawing a fixed blade), there is an element of truth to this - the knife needs of most being unchanged or lesser than 100 years ago, the industry needs to continually refine itself to stay in business.

I wonder if, to a lesser extent, that happened with slipjoint patterns. "Ehh, I got these designs, boss, what should we call 'em?" "Hmm, call that one a spaying blade, call the other a cotton sampler, extend that ricasso out and the big blade'll be perfect for sticking bales". Like, I think the design is very cool, but was the world really crying out for the big, goofy, Cotton Sampler blade shape? The folder, not like the Ontario knife. I'd like one of those with the slipjoint axe that was here the other day, glad Rough Ryder keeps those shapes alive.

This could be us, Case, but you playin'

Like you say, the style of knife varies with the part of the country. I've used a large stainless steel Buck stockman's spay blade (easy to sterilize) and a disposable scalpel. The main thing I want is small and razor sharp. One difference between the way you are doing it and my days with a small herd is that I usually worked on them when they were only a week or two old. Easier to take them to the ground when you don't have horses. My dad never liked the blood and gore of cutting so he used both a clamp and bands. And every so often he missed a nut and paid for it at auction.
 
But the word "spay" refers to an ovariohysterectomy, not a castration.
I am having Internet trouble and have not yet found any etymology for "spey" other than a river in Scotland.

A knife with a blunt, rounded tip is useful when you are worried that you might accidentally stab someone, such as yourself. I often use a sheepsfoot blade around livestock for the same reason.
