Reddit mentions of Weishi Safety Razor and Travel Case with 5 Blades.

It isn't clear what you're asking. Do you want to try a different razor instead of your DE89, or are you asking for recommendations of razor blades to use in your DE89?

As far as razors go, the DE89 is not aggressive at all. You could try a cheap Chinese TTO like a Baili or a Weishi, but it's really unlikely that you're getting irritation because your razor is "too aggressive." If it's blades you're asking about, there's no such thing as "mild" or "aggressive." Just try a variety of them and pick which feels best to you.

But the fact is that the problem is likely your technique rather than your equipment. You say your lather is fine, but you don't mention what you're using or how you're using it. And if you really weren't using any pressure, you wouldn't be getting razor burn or weepers. The reason most people use too much pressure is that it's the natural way to compensate for incorrect blade angle. Get your lather and your angle right, and everything else will follow.

Using a DE razor is an acquired skill. Rather than blaming your tools, focus on learning how to use them well. Don't shoot for perfection right away; just try to make each shave a little better than the last. With continual improvement you'll eventually get the results you're looking for.

Your Van Der Hagen razor is a rebranded Weishi and isn't terrible, just cheap. I used one for 2 years straight and while I could get good shaves out of it, it was very mild and inefficient for me. That basically means it didn't remove much hair (especially if I had more than 3 or 4 days of growth) per pass.

With that said, it was still a damn sight better than any cartridge razor I ever used. I echo the sentiments of others here, you can find better options that are still inexpensive at sites like https://www.maggardrazors.com .

For all intents and purposes it's a 60's Superspeed. Feels the same in the hand as a Superspeed. Weights a little more than a Superspeed. In terms of aggressiveness, it's between a red tip and a Superspeed.

From what I read previously, these things are nickle-plated stamped brass, just like a vintage 60s Gillette. I wonder if Weishi bought some old Gillette manufacturing equipment.

I bought the black one, which costs more. If you get the standard silver one, it's only $9.98 on Amazon.

If this was the only razor I owned, I woldn't have any complaints.

Weishi 9306 (short handle) with travel case or a Baili BD176.

Travel case/tube for my synthetic brush.

Soap in a used (or unused) deo container.

Two 50ml spray bottles for my aftershaves.

A pack of Gillette Guard as a backup, in case I can't find DE blades at destination.
It's also great to shave my hairy silver back.

It will take you a little while to get used to (mostly the weight of it. These razors are much heavier, which I actually ended up liking cause I think it gives me more control) so just start out slowly until you get used to it! If it clogs you can just open it up a little, run it under some water, and close it again.

My only problem so far is that, with the model I have, my palm rests against the knob that opens the blade guard and gradually opens it up a little as I'm going over my legs with it, so I have to stop every once in a while to make sure it's still closed tightly. If it isn't clamped down, it will be more likely to cause rash/nicks. It isn't something that really bothers me, though, and you might have a different grip or find a different model which doesn't cause that issue, but I figured you should know in case it would be too much of an annoyance for you.

If you do make the switch, good luck with it!

Looks like a Weishi to me.

I came to recommend the same thing. Keep things low tech and low electricity.

You can get much cheaper options for shaving. $10 Omega Synthetic shaving brush that will hold up to travel better than a nice badger/boar brush. $12 Weishi twist to open razor that has less parts to deal with than the Merkur (twist to open versus 2 pieces that come apart). And if you're a weight weenie, get a shave soap puck that can work as a body soap too. Wash your body, then hit the brush on the puck, lather your face, and shave.

For beard trim, use some scissors. For nose/ear trim grab one of these. The DE blades are normally 15-20 cents a piece and you can normally get a few shaves out of each blade.

That should be a nice grooming kit that does not require any power and really should last you for the rest of your life if you take care of it.

It's a re-branded Weishi. I have used the exact model for 3 years now, and get a decent shave out of it. Perfect piece to step into DE shaving. Highly recommend doing some research on soaps, and picking up a sampler pack of blades to see what is going to fit your routine best.

Well, here's something I found on amazon:

http://www.amazon.com/Weishi-9306-F-Twist-Double-Safety/dp/B001D4Z87W/ref=sr_1_1?ie=UTF8&qid=1396061758&sr=8-1&keywords=weishi+razor

It's super similar, and it's 10 bucks (not sure what the shipping will be). For a brass razor, that's not half bad, and this looks like the exact same thing.

I know /u/betelgeux said it's similar but not the same. That being said, even if it isn't the same, from what I can see it looks really damn close.
