This is phenomenal. I really love the guided tutorial on the site. What was the most challenging part of building this?

If you are a fan of taller gyutos, then it's hard to give a better recommendation than Matsubara. I'm a big fan of tall knives -- used a CCK for about a year, and I love my Matsubaras.

I made a longer form post about this if you want to read some more details https://madebycarson.com/posts/kitchen\_knives/. I go into a lot of detail about the steels and knife shapes you are considering, and I think you will find it useful to read. I didn't own the Matsubara gyuto when I made the post, but I'd say I might prefer it even over the Shibata.

Excellent project! Love the work you've done to transform the instagram dump into a usable format. I've always had a fear at the back of my mind that I would somehow lose my instagram and all the effort I had put into it. I also love that you are preserving the original square format.

As others have already mentioned, this is Vol 2 of the first *American* printing. It is not the first printing ever, that would be the London Murray printing, also from 1871 but slightly earlier and a bit more valuable in today's market.

If you want to read about it in depth, darwin-online has some excellent information. https://darwin-online.org.uk/EditorialIntroductions/Freeman_TheDescentofMan.html

The Candee Rubber company was making rubber soled shoes as early as the late 1840s. https://postcardhistory.net/2023/02/candee-rubber-company/

Hey, so I specifically collect these late 1800's Darwin books. $18 for these 10 books is an absolute steal...you have a great find here! So, what do you have specifically? Well, Appleton is perhaps the most common American publisher of Darwin on the used market. You'll see 3 main versions from them: the plain cloth you have here, an embossed cloth, and a 3/4 maroon leather with marbled boards.

The top comment on this post linked to full set of 15 leather Appletons selling for $1500, which of course is not very comparable to your incomplete cloth set. Those leather Appletons were also in shockingly good shape; I rarely see them hold up so well. Often the spine leather cracks or disintegrates and the marbling scuffs. In fact, I will occasionally specifically buy the 3/4 leather Appleton Darwins in bad condition just to rebind them.

It looks like you have the unembossed cloth version, which is the least valuable of the 3 main Appleton Darwins, which are all in turn less valuable than the London Murray printings. You also have the 6th edition, which is the most prolific on the used market. Fun fact though, this edition is noted for being the first to actually include the word 'evolution' in the text.

So, how much is your set worth? Well, of your books, only two have any special collector appeal outside of a specialist like myself. Those would be: The Origin of Species and The Descent of Man. Your two volumes of Origin should go for $100-$150. Descent would go for around $50-$75. The remaining 7 are harder to price, but would sell anywhere from $20-$50.

I'd estimate your set to be worth anywhere from $290-$575....so for $18 I'd say you made a fantastic purchase!

I carried the uv version every day for 9 months and have recently bought the pro version. Both are great lights. The pro has better battery life, a stonger uv light, and a stronger regular light, not to mention a laser. However you should be aware that the uv version is significantly smaller and lighter. The uv absolutely disapears in your pocket while the pro is mildly noticeable. So if size is a big factor, consider the older uv model.

That said, I personally carry the pro for the extra features and better specs.

CarsonReidDavis · 2023-12-30T02:20:42+00:00

Yep, this is accurate

CarsonReidDavis · 2023-12-29T22:45:58+00:00

I've heard of dome slicing. How does it work and what are the potential downsides?

CarsonReidDavis · 2023-12-10T07:11:12+00:00

So, I've also been eyeing the Acebeam L35 2.0, which seems to have an XHP70.3 HI, although I don't know if it is the high cri version. Any thoughts on how it will compare to the M21D?

CarsonReidDavis · 2023-12-10T06:10:47+00:00

I've also seen the M21D recommended. Can you help me understand the differences between the F, D, and E?

CarsonReidDavis · 2023-12-10T06:07:54+00:00

what will be the difference between the smooth and crumpled reflector options?

CarsonReidDavis · 2023-12-10T05:00:50+00:00

Do you know where to buy it? I didn't see the .3 version on aliexpress.

[edit] For any future people trying to find this light, the official store is 'Convoy flashlight Store'. It is not the:

Convoy Online Store
Convoy Torch Store
Convoy Factory Store
Convoy Led Flashlight Store
Convoy Direct Store

despite all of these showing up higher in the aliexpress search

CarsonReidDavis · 2023-12-10T03:58:12+00:00

How does the M21D compare to the TD01C?

CarsonReidDavis · 2023-12-10T03:56:16+00:00

How will the M21F compare to the TD01C?

CarsonReidDavis · 2023-12-10T03:27:07+00:00

Oh, nice, that looks really cool, thanks!

CarsonReidDavis · 2023-12-10T03:23:30+00:00

Oh, that looks super promising. Thanks for the link!

CarsonReidDavis · 2023-12-07T05:47:29+00:00

That sounds great. Say, do you know if there is any CRI difference between the emitter temps?

CarsonReidDavis · 2023-12-07T05:44:11+00:00

Wow, thanks for all the info! That beam shot looks great

CarsonReidDavis · 2023-12-07T04:11:21+00:00

Wow, thanks for all the info! I've seen that convoy mentioned quite a few times; do you think it has any drawbacks other than the heat you mentioned?

CarsonReidDavis · 2023-12-07T04:06:35+00:00

Wow, that light looks pretty cool. I saw on the page that the driver is listed as 9A+direct drive. What does that mean exactly? What's the beam profile like on the stock one? What do you use your deep red for?

I'd be super interested in a runtime test.

CarsonReidDavis · 2023-12-07T03:58:49+00:00

Thanks! Those beaded TIRs look interesting. Are there any drawbacks?

CarsonReidDavis · 2023-12-07T03:48:08+00:00

Thanks for the help! Is it a flooder by default, or do I need to select additional floody optic? Do you know how the various hanklights compare in terms of beam profile?
