OSS

I replaced the handle with the MR5, nothing wrong with what it came with but the MR5 was made for this head for grip and dexterity and was just a better choice.

But you dont shave with the handle, so to the head. You get 2 shaves with this, depending on the side you use and i use both in a shave.

I used a feather blade and im getting BBS, irritation free and didnt need to stop after the second pass and use my second razor, the mild DOC (double open comb) from Phoenix. I cant do 3 passes with my skin with the R41 or 37C as the irritation kills me for hours afterwards and i like a smooth finish shave.

Buy if you can, iKon often dont have stock but you can find them online. The DLC or TEFLON coating looks good and it might slide a LITTLE better but i wouldn't pay more for a DLC. Also dont screw the handle on too hard as its made from aluminium and it will last a lifetime if your carefull...

Ikon makes quality razors. I have been very satisfied with each one I have.

One of the best razors I've ever used, and immediately elbowed its way into the Rotation. [Thank God for RAD!]
Be aware that this is a big razor, especially with the OSS handle - virtually the same size as a Merkur Futur. The head is markedly less bulky, though. IKon manages to cover the blade "ears" without the enormous overlap of the Futur, and the blade corners are not exposed as they are with the Futur.
The dual head is indeed a brilliant idea. I'm used to an OC, so tended to favor that side, but the closed side is well-suited to XTG passes. The closed side seems to work better if you stretch your skin; the open side doesn't seem to care much either way. Both sides of the iKon 101 seem to self-clean better than the Gillettes, and rinse easily.
Nothing but praise for the handles, both the OSS and the Bulldog. Their knurling makes your grip very secure, and the weight adds control as well. I have a slight preference for the Bulldog, as it is more maneuverable for work around the neck area (the extra length of the OSS requires one to be very conscious of the blade angle).
A note on the ratings: It's odd to rate a non-adjustable razor on adjustability, but there's no n/a ranking; my ranking it 7 is based on its versatility, what with the two different sides. Blade replacement is slightly harder than with an older-style (Gillette) 3-piece, since the ears don't stick out, but keeping them unexposed is an advantage in my book. Re the "aggressiveness" rankings, is a 10 "behaves like a straight razor", or is a 10 "exactly the right balance between cutting and danger"? IMO the iKon 101 does a good job of getting at the stubble without bringing the skin with it, but there are other razors that will shave closer on a single pass. The "10" on grip is the only 10 I've ever awarded on any B&B ranking; I simply don't see how a handle could be grippier without adhesive, and the thickness is well-nigh perfect.
In sum: an expensive razor if your frame of reference is used Gillettes, but well worth the money in my estimation. Just do what I do with all my other RAD/SBAD purchases - rationalize it by amortizing the cost over the next five decades. Done that way, it's dirt cheap. Cheaper than dirt if you can find a blem deal.
