Thought someone might learn from a couple of mistakes I made just in the last two days; at least the new guys might. I'm sure everyone else already knows this stuff so I guess I'm slow to learn.

An 18" Dui Chirra that I had received had some minor scratches across one side near the spine of the blade. No worries, I put on an 8" buffing wheel that I use with Red Rouge, added some new compound, and went to polishing. The scratches came out nicely, and I was about to turn the buffer off when I noticed a few more minor scratches down by the edge of the blade. Rather than doing what I KNOW to be correct and holding the cutting edge down and away from the rotation of the buffer, or at least vertically in line with the wheel, for some dumbass reason I held the edge UP. I actually got away with this for about 10 seconds, and just as I was about to pull the edge away from the downward rotation of the buffer, the wheel grabbed the sharp edge, which proceeded to shred my new buffing wheel into a thousand threads. What was left of the wheel then grabbed the edge of the blade and spun it around in my hand and slammed the cutting edge up into the cast iron underside of the buffer. DOH!

Now my beautiful new khuk had 3 nice dented rolls in the blade. I thought I was going to be sick looking at the damage, and of course felt like a total noob.

In any case I was lucky, as using a large 12" long burnisher (like the chakma only more so) with the khuk in a padded vise I was able to get the edge almost exactly back in line with a half-hours worth of effort. Thank God it was a solid edge as the whack it took into the buffer body was tremendous. Finally a resharpening removed all the incriminating evidence and it looks as good as new.

Luckily for me also I was wearing gloves. If the khuk had spun in my hand any differently, it could have taken a finger off or other bits of my arm, and / or ruined the khuk as well, which would have been even worse! Just a word to the wise.

SECOND thing happened this morning. I have always thought of the loose scabbards on some of these khuks as only a minor irritation. Sometimes I fix them with a leather glue-in and sometimes I don't. This morning I was looking at a 14" BDC and set it down on the edge of the bookshelf. It started to fall and I grabbed for it and got the sheath no problem, but the handle was pointed down and the loose knife in the scabbard kept on falling. My little finger and index finger were under the mouth of the sheath, and of course for once Bura had decided to give one of his knives a razors edge! As it fell it sliced neatly across the first pads of both fingers. Ouch.

So, I am spending this morning hot gluing in black or brown leather shims into all the scabbards that I have been ignoring that are loose fitting! Don't have to bother with most of the old stuff I have, or anything by Sgt. Karka, but many of the others are hit or miss as to looseness.

It's funny, but not one HI sword I have has a loose scabbard, it's only some of the khuks. With the fat habaki bolsters you would think fitting a scabbard would be even easier (?), but not so.

Anyway, live and learn. If this thread prevents one of you from making the same mistakes it will be worth it. (Or I should say, if just one of you makes these same mistakes I'll feel better! :) )

Norm
 
Trying to catch falling stuff can be dangerous. I once tried to keep a jar of Ragu from hitting the floor and breaking by slowing the fall with my foot.
Guess what? The jar didn't break, but a bone in my foot did.

Next time, let the stuff fall where it may.
Just make sure that you don't have a dog or relative nearby when something falls.
 
I think when you're in the position of grabbing at an upside down knife by it's sheath to catch it you've already done bad. Or you're on the losing side of the event.

Some sheaths are too tight, and some are too loose, but the use of the blade dictates how you define those so it's impossible to make a sheath right for everyone, even if there wasn't shrinkage or warping.


I'm more annoyed at blades that must be worked out of the sheath than blades that come out too easily.

I'm glad you weren't hurt. I know how it is with power tools- they're addictive and promote some laziness, or their ease suggests the idea of 'just one little spot more."

You guys have made me downright paranoid about grinding wheels.

Thank you for sharing this story.

I have very quick reflexes and I will have to be somehow cognizant of how they can hurt me should I try to unthinkingly catch a falling scabbard.

Good title for a book, that...To Catch A Falling Scabbard :D
 
I fear buffers and spinning blades. When I use a table saw, I use push sticks. I don't want my fingers near the blade.
I have read that buffers are among the most dangerous tools in the shop.

Anyone know if it matters if you use a pretty hard felt wheel? Is this safer, and would it work for polishing a blade?
 
I'm scared to death of buffing wheels.

Svashtar, don't feel like the "Lone Ranger". I tried to buff up my 30" Kobra. I lost it in the wheel! Just imagine a 30" blade flying in the air. It was quite humbling experience, and no I wasn't drinking when it happened. :D

I had a drink after that happened though, I was shaking a bit.
 
If it's not the most dangerous tool in your shop the buffing wheel has to rate among the top three. BirGorkha has had more buffing wheel accidents than any other.
 
I was thinking about getting a buffer tomorrow. Probably still will later on but think I'll experiment with hand buffing for a while. Prefer the satin finishes anyway. Glad you weren't hurt Norm.

Never take your eyes from a table saw while it is running.

Never talk to anyone when using power tools.

I had a shop teacher who lost two fingers demonstrating the safety features of a table saw.

This happened many years before I met him. He used his stumps as an object lesson to us.

We responded by saying, "Give me three.' And offering to shake hands.
 
There is a sword maker/dealer I know who sells knives and swords that start at 150$ and go up quickly to more than 10,000$.
Antiques, custom pieces you name it.

Anyway, whenever a potential customer asks to hold a sword, he says "yes, but always keep the point of the sword pointed at me and if it falls, let it fall. Don't try to catch it. I can polish out the scratches in a 1,000$ sword , but there's no fix for a cut off hand."
 
Glad it wasn't worse Norm...

I've worked with buffers and other power shop tools since I was a kid...a habit I have had since I was taught to (as a toolmaker) is that every time I am set up and ready to start work (yeah, I sometime do this 100 times a day) and hit the switch, I stop and compose myself as a martial artist might. I take a moment to scan the work area, review the actions I am about to put in motion, remind myself of the clear zone(s) and generally focus my attention to the task at hand and not a single other thing.

I have no idea of how much time I have wasted with this ritual...




But I am very aware of how much time I have saved in trips to the emergency room or worse.

That one's gonna give me nightmares... :eek:
 
Thanks for the story. Every time I turn on the buffer I have to remind myself just how scary the darn thing is and how quickly it can turn on you, a very unforgiving tool :eek:
 
You're not the only one to have this happen, a few days ago I was holding one of those loose-fitting kuks in the sheath, the knife was about horizontal as I held it, but being handle-heavy it began slipping out the back and towards the floor. Instinctively I grabbed for it and felt a sting on the inside of my finger. When I looked there was something liquid on my finger. When I looked closer it turned out to be oil, not blood. Lucky me. Now I will have to do the leather glue-in thing, which I have been avoiding since I don't have any little pieces of leather lying around. Anybody have tips where to easily get leather shims?

Well, I lucked out. My company recently bought about 30 new leather chairs for the conference rooms. At the bottom of each chair was a 3" X 3" piece of black leather hanging by a plastic tag, provided as replacement patch material in case the chairs got holed. The facilities guy took them all off and was going to throw them away but I grabbed them all, and they are perfect for the task. I also have some brown strips from an old gun belt that I use for the brown sheaths. A little shoe polish of the correct color (black for black of course, but Cordovan works much better on the brown sheaths than standard brown shoe polish) blends the shim right in nicely.

Try some furniture stores around back and ask whoever is there if they have any of these patches. Seems like all leather chairs and couches come with them now.

Good luck!

i've learned some pretty good reflex skills from working with a bm42 balisong in my underwear over about a months worth of time (think theatrical dance move, throwing your legs and hands outward and your hips bacwards, then sitting there breathing hard for about 5 seconds)... nothin like going to work at subway with 6 new cuts on your hands... the dish soap loves you for it :(

with the added weight of the bm42's steel handles, if you try to catch it, your garrenteed a 1mm deep+ cut or more. ive had khukuries start to fall out, but i can normally catch them with their sheaths...



one other note about knife safety in generally, and this definitely goes for khukuries (my incident involved an ontario spec plus frontiersman, newly sharpened (a bizarrely sharp knife)).

if you get sap on your knives and intend to clean them off with iether gasoline or lighterfluid, and their sharp, BE CAREFUL. do not run you hand lengthways along the blade. getting a cut is bad enough, covering it in gas is even worse.

man.. im reminded of the scene in so i married an ax murder where mike meyers is using the buns of steel excerisizer (2 bars on a springed hing that you put between your legs and squeeze), and it goes flying into the backround as he's watching tv...

halarious on film, but im not sure how much id be laughing it that happened with my 30 ang khola...

Nasty, I don't think you wasted a single second. If you are sitting down 100 times a day, or just plain often, to work with power tools, that mindset you described above is the ONLY way to do it.

Glad you're ok Norm. Thanks for sharing!
Glad the blade cleaned up ok too.

Norm, you finally convinced me. I went and superglued a leather shim in each of my loose scabbards today. (The seax got two.) Even the Kobra, which was the loosest of the bunch, will not fall free with any amount of shaking. No more fastdraws, but still pretty-quick-draws. I've never had one fall free on me yet and didn't want one to.

As for buffers...well, they used to snatch things away from me all the time when I was younger. I never gave it a second thought. A few years ago one took a hammer away from me and thumped me good. I really haven't had the testicular fortitude to use one since. If I can't do it with #2000 sandpaper, it don't get done. :D
 
reminds me of why I prefer hand tools to power tools.

As was said once on the Old Tool forum, it takes a moment to cut off a finger with a tablesaw. It takes determination with a handsaw.
