No. 3570 is really a band apart. Super solid. I think thereās brass in the upper hex. Feels like a classier r600.
I wasnāt sure what to expect with that one but you are correct! Itās a very well constructed piece. I do really like the 3150 the best though.
It reminds me of this guy who is very difficult to find imo, but very inexpensive. XENO CX 0.5
Well, youāve done rather nicely here with LION, DWD. Respectable collection, particularly the 34xx series.
Yeah, I almost went for a 32xxā¦ but thankfully @drifand warned me off.
Back a good 10 years ago when I was just getting interested in vintage Japanese mechanical pencils, I didnāt even pay attention to names I didnāt recognize like Uchida, Newman, and LION. The few examples Iād come across in open category browsing didnāt impress me. It didnāt occur to me that there might be better models worth searching out. I did wise up enough in time to grab a few from Uchida and Newman before the painful collector surge of 2020. But I am finally going to experience 2 different LION models in my next shipment. A 3430 and a 3570. Canāt wait!
If your 3570 was the auction a couple weeks ago, Iām glad it was you that got it. You got a bit better deal than me because someone kept bidding on mine at like 2 minutes (Why?) so it kept extending and extending. I watched your auction.
There were 2 of them for sale by the same seller. I watched the first one and noted the 2nd highest bidder. They appeared on the 2nd auction and yep, same exact bid amount. So I figured Iād get it for the same price as the other auction. But noā¦ another bidder showed up. I was so POāed. Butā¦ thankfully they didnāt push. it was only another Ā„600, which is nothing.
Yeah, in the deep past, the prices for the 3470 have gone even higher. Pretty shocking. At one point, hitting upwards of Ā„18,500! (LINK) Whatās weird is the other sizes are extremely scarce. For some reason the 0.7 mm has been much more common.
I love Lion designs. I wish I had a few with green or blue stickers.
That 3570 looks impressive indeed; really stands out of the crowd.
Usual huge downside: the non-removable clip (why? WHY???)
Also, I should have been able to get a Xeno (via another āKnocoā with whom Iām in contact with here), but it will be here in a few weeks; I am very curious after i spotted the Faber-Castell version, and I am looking forward to trying itā¦ 
I had a bad experience with a FC āXenoā. It was called a TK Metal and it reached me from Amazon Japan missing the rubber lead retainer. So what I got was like a 0.9mm lead holder. I donāt know where I chucked the pencil in disgust. My other Xeno have been ok.
Nice work with the 2000 erasers. I like the fancier nose cone version a lot. It asks the question: Why keep things simple when you can complicate them?
Their erasers are even different. I canāt say no to a good retractable eraser when it comes around.
Yāall are nutsāI love the 32XX. Aesthetically, the 34XX series is gorgeous, but the tip is quite slippery (relegating these pieces to display-only for me).
And itās a shame the 3570 was only ever offered in 0.7. Itās the coolest looking LION and stands out in any collection.
Whaaaaat!
Wow, I have another LION catalog with only the 3570 shown. Since Iāve never seen another lead size of 35XX for sale, I always assumed it was the only one!
You WILL find them all 
And how nice are those stickers? The LION sticker loadout is one of my favorite things in pencildom.
Iām hyper focused on Faber Castell right now. These will have to be like your side quest Mitsubishi 1052 pen/pencil search.
They are unicorns, basically.
Iāve searched through the Aucfree database and the 3570 turns up a good bit. The others? Just one 3550 in 2019 (LINK) and not one single 3530.
They are not just pretty, they are necessary. Without the stickers, you canāt really tell the lead sizes apart. It wasnāt until later examples that LION finally printed the model numbers on the body itself. Best examples of this improvement are the 32x0 and 31x0. Older versions lacked the printing.
