A while ago I mentioned I was going to attempt making a knife for the first time. Well, I did.

Apologies in advance for there not being many photos of the process - steel is really messy to work with so I mostly kept my phone safely out of the way. I'll try to get more pictures next time, although there are plenty of videos and picture tutorials around if people are super interested in the process. I shall endeavour to describe what I did in text, however.

I started out with a bar of 01 tool steel (wiki) which I cut into a rough knife blank. This I then hit with a ball hammer a load of times to get some texture. Then I used a belt grinder to put a bevel on the edge side, although only enough to thin the knife down to roughly the right shape, not actually sharp. Once that and a few other minor shaping tasks were done, it was time to heat treat it.

Heat treating changes the structure of the metal to make it harder. Hard steel will hold an edge longer, but it does make it much more difficult to work, hence doing most of the shaping before heat treating. To harden steel you need to heat it to a particular temperature, which depends on the exact alloy being used but 'bright orange' is close enough. Fun fact - when steel gets to it's 'critical' temperature, it stops being magnetic, so that's another way you can test it. The steel is then quenched, this one in oil, which makes it hard.

Hardened steel is very brittle so it's usually tempered after hardening. For 01 steel that means putting it in an oven at 160-200C for a couple of hours. You lose some hardness but you gain back some toughness and flexibility.

After tempering, cleaning, polishing, polishing and so much polishing. Steel is so dirty and difficult to work with compared to the silver, gold and copper I'm more used to. But eventually, and after glueing and bolting a sycamore wood handle on, then giving it a final sharpen on my wetstone, I had a knife.

It is a Japanese-style Nakiri knife. Usually used for cutting vegetables, it's really nice to use. Lightweight and agile, the balance is nice and it's comfortable in my hand. It's not perfect and there are a few things I'd do differently but I can see myself using this on a daily basis. More pictures

I have already laid out and started shaping my next knife, which will be a slightly more complicated bunka knife

Any questions, please just ask and I'll do my best to answer.

I don't watch T.V very often, but do - when I'm up (which is infrequent given I'm outside the U.S) - watch the NBA. Recently I've had a little time so have watched a few games live. Doing so, I was quite taken aback at how commonplace humour and meta advertising are nowadays. Is this just a U.S thing?

Is there any research out there on when and why advertisers started doing this? Seems like every other ad shoots for either humour or "we know you know this is an ad, you're clearly smart enough to realise that, so smart in fact you might want to buy into our brand". Whatever the case, as ever, grateful for resources/discussion from those more in the know than I.

EDIT: A good example that is equal parts humour/meta is LeBron James' Super Bowl Sprite Ad.

Written by Neil Gaiman and illustrated by various brilliant artists, The Sandman series has definitely had an enlightening and positive influence on my life. Much like Dream will say, it feels like the comic speaks true words.
For me — and I struggle with having had no role model — this comic series provides exactly that, in a way.

I wonder, whether people here have read it, or bits of it, and what their opinions are.

This is a recurring post to discuss programming or other technical projects that we've been working on. Tell us about one of your recent projects, either at work or personal projects. What's interesting about it? Are you having trouble with anything?

Here in Brazil we have many unique song genres not heard past national borders. The most well known ones are Brazilian funk (completely unrelated to American funk), Pagode e Sertanejo.

Russian hardbass and British Chav Rap are good too.

A while ago, maybe like a year ago? There was a thread and two websites were linked to that were basically puzzle sites. As in the sites themselves were the puzzle and you had to find clues in the site to get to the next page. It was very cool but I managed to lose the link and was hoping someone might know what I'm talking about. We ringing any bells?

In a time of ancient legends, Androcles was a runaway slave.

He took shelter in a cave where a wounded Lion lived.

By removing a thorn from his paw Androcles cured the beast; The Lion was very pleased.

And then The Lion ate Androcles because he was a fucking lion.

Looking at the Activity page right now, there are 2 different pointers to 2 different articles about turning off auto-play on Netflix. I totally get why people are excited about this!

My question is, do we care about duplicates? Some forums ask people to notify a mod and they combine the threads. Others just let them be. Is there an official stance on this here?

Ask not for whom the cradle weeps; it weeps for you.


O sly kitten, O accursèd cat, cry,
cry for the weft and the warp of the world; cry,
cry for the sin and the sorrow and suffering; cry,
cry on the bloodshed, but more on the tears; cry,
cry for divisions, and ill-wrought connections; cry,
cry for the laughter, so far out of reach; cry.
And in crying find solace; peace——rhythm——be still.

                                               cry 
and cry——cry for the widows and widowers, woven together forever,
by weeping and painless heart-let.
   But your pain is not theirs.
   For, though burdened with truth, you will never be cut 
   by the serrated and blunted edge of polite fiction.
   Enough!


When the cat's in the cradle, the mice will play,
And I hope that they fly far——far-far away.
But the tears of the kitten forever abide,
and someday they'll catch you.
               will you take it in stride?
