December 16, 2010: What I said below still applies. However, a little practice, the discovery of "pulling up" slightly while slicing, and knowing when enough is enough makes this the best tool that I've used for callous removal in 25 years.

I've had trouble with my feet and shoes for years and years. I used to get blisters. Now I get callouses and, as anyone with deep callouses at the ball of the foot will tell you, they kill! Try walking with a pebble in each shoe and then add one to the little toe just in case you're a sadomasochist. That's what my lousy feet have been like, and this from a guy who played racquetball. squash, and tennis for over 45 years! (Throw in 5 years of marching including "extra duty" for those who know the old military.)

Of all the doctors I don't mind going to, the podiatrist is the one that I mind the least. You come out feeling better than when you went in. But who wants to do that on a weekly or bi-weekly (or is it semi-weekly?) basis. That's how quickly my callouses recur. This Tweezerman Safety Glide with rasp is the best tool I've found. The fact that it's a combo and that the rasp when exposed covers the blade makes it a great tool, and for under 10 bucks!

The rasp is almost as good as what my mom used to use. Her's was a 3" oval and remained sharp or I should say remains sharp to this day. Still, having one tool for cutting and one for smoothing is great.

I want to disagree with those who say to do this when your feet or callouses are moist. I found that the blade binds because the skin around the callous IS moist. Best to have the blade glide over the raised callous bit by bit than to get caught at the base of the callous.

Btw, nothing will ever make my feet smooth, and I don't really care. At my age, my feet get less exposure than my knees or double chin or anything else I no longer care to hide. (Besides, it's winter and Levis are the order of the day. That covers my knees. If I live to be 100, my belt will ride so high that my chin may well be covered, too - just like I used to see in Miami Beach. SO, one last tip. If you want your feet smooth so that your socks glide on over your feet, use a podiatrists "wax" daily. There's also one put out by Johnson and Johnson.

But now this review is getting a little squirrely. I just hope that there are men who understand and perhaps empathize with my foot problems. Callouses are not just for women. We get 'em, too.

Since, I'm about to erase my previous review, I'll reiterate what I said the first time. This uses a razor blade. Treat it as such. Don't cut too deep. Take your time, especially when doing the opposite foot, i.e. the one ON your dominant side (right foot for right handed people etc.). Do this in as much light as you can get on the bottom of your foot; not always easy especially when your - my - stomach casts a shadow. Leave a little callous because, if they're below skin level, in a weird way, they actually cushion the bone ... for a few days.

My dad had perfect feet. I inherited his nose and ears and sense of humor. Thanks, Dad.

My mom had perfect skin and beautiful eyes. I inherited her feet. But I also got her Tweezerman rasp. Thanks, Mom.

This thing works! I had about six inches of callouses (I'm exaggerating, of course) after moving to NYC and working in service. Nothing worked. I had the PedEgg, but it simply didn't work as well as I needed.

The first time I used it my skin was way too tough, it barely worked. Also I accidentally took the whole thing apart and spent 45 minutes and a YouTube video to get it back together.

But the second time I used it (after figuring out how it works)? Reams of dead skin came off. I got a little over excited and gouged myself though so beware! That's why I took of a star (as well as the "wtf" moment you get when you first take this thing out of the package), even if it might be user error: if this thing catches a chunk of skin it will rip it off. Not only that, but it leaves uneven skin where you stop working on removing the callouses. The rasp smooths this but it still actually causes some pain until I can even it out (after the first gouging I try to wait a few days in between using it).

BUT. it's done what nothing else could in the past several years so I still say this is a great product, even if it isn't user friendly.

This is definitely the best thing that has ever happened to my feet.

I had rough skin on my heels since I can remember. When I say rough I mean the ugly thick horseshoe-resembling layer of grayish substance covering my heels - catching on carpets, painful to walk on, occasionally cracking, stocking destroying. I actually was too embarrassed to go to a salon for pedicure.

I tried everything that I could think of - tons of different files and rasps, pumice stones, creams and lotions, electric devices. I just wasn't able to get THAT off my feet - no matter what I did. I've never seen pink healthy skin on my heels until this Tweezerman Callus Shaver happened to me - and my life changed.

It was somewhat tricky to make it work at first but I was determined and did figure it out. The problem was not to understand how the shaver works but to actually make it work, because pressure, angle and force are the variables that make all the difference. You need to try many times to really feel how to move your callus shaver and make it work efficiently. The learning process was on the longer side (20-30 minutes maybe?), and I cut myself badly once (as with any razors, never move your shaver sideways!) - but I didn't care. All I needed was the result - whatever the price.

I spent at least an hour in a bathtub shaving off strips of dead skin layer from my heels. And after I was done - ta-da! My heels were all pink and soft (and unevenly shaved) - for the first time in my adult life! Unbelievable! I still remember that amazing feeling that so many people take for granted - stepping on your heels and actually feeling the floor, even feeling the air! Wow! I'm used to that feeling now and don't notice it anymore.

Two years have passed and my heels have been very happy. I use my callus remover once a week - after I shower, because your dead skin needs to be very soft to let the razor cut through it. The central button of my shaver broke causing the cover to fell off but, again, I do not care. Who needs the cover anyway? The shaver still gets the job done and I love, love, love my callus shaver!

As for the negative reviews of people who were not able to use the device, I'll say this: just keep trying! As soon as you figure out how to use your callus remover you will be happy you have!

And one more thing: when replacing the blade, it's easy to put it upside down - this hides the cutting edge of the blade and prevents the whole thing from being able to shave. Make sure you can see the blade edge when you have assembled the thing!

First of all, I have terribly callused heels. They crack and are sometimes painful. I've tried everything and can't find anything to get rid of it. This product does the trick. It took several times of doing it because I was very careful to only remove small amounts of the callus at one time. If you remove too much, it is painful (even if it doesn't hurt at the time you're removing it, it will the next day).

Anyway, I am giving this product only 4 stars because THERE ARE NO INSTRUCTIONS! I don't know about you but I think instructions are important when you're playing with razors. Immediately after opening the package, I was trying to figure out how it worked and accidentally released the razor blade. It fell and sliced my finger open in the process. It was not a small cut either - it bled profusely and was painful for a week. You won't find instructions online either. The best thing to do it just look at the image of the product and set the razor so it looks like that.

This product works best if you use it when your feet are slightly damp (like 5-10 mins after getting out of the shower). If you do it while they're too wet, it won't work. The rasp is just ok - I've used it every now and then but it doesn't make a noticeable difference for me. I usually just use the shaver for removing the callus them use a pumice stone to smooth out the area.

I didn't buy this for my feet. I bought it for my hands. I'm also a man. And I've got manly hands, that I need to keep from getting too grizzly. And this things helps with that.

Whether you're doing weight lifting, or doing higher intensity interval training such as CrossFit, your hands are most likely getting some good calluses due to barbells, dumbbells, pull-ups, etc. The thicker your calluses get, the more likely they are to rip open during your workout. This Tweezerman Callus Shaver helps keep those calluses from getting too bulky. As long as you can figure out how to use it after it arrives...

How the heck do you use this things? I opened the package and tried to give it a go, but there were no directions on usage. After viewing a video online, I finally realized: You NEED to REMOVE (pop off) the little white piece from the blade side, in order to be able to reveal the blade. Make sure the blade is also pushed up all the way. You'll then see a little crevice between the metal and the blade. This is where your skin will get under the blade and shave off. The white plastic piece covers this area for safety when not in use. With the white piece off, if you slide the blade DOWN, it will remove the blade for replacement (or you can also rotate it, as there are two sides to the razor...and only one side is used at a time).

Shaving of the hands works pretty well with this, especially if your calluses are built up pretty well. But some times you do need to apply a bit of pressure and maneuver the device. Or do another couple passes after using the rasp. Trimming a few of the skin fold areas in the middle of the hand/palm can be a bit difficult, but still manageable.

The rasp side is also useful, and you'll be surprised how much dry skin you end up flaking off (into the device)...even if it looks like it's just roughing up your hands. It's not as cheese-grater like as I expected, but it still seems to work. It will basically work like a rough grit sand paper.

This thing does work great, and definitely it a must have at this price...especially if you don't want to skip a workout due to destroyed hands. Just because you have calluses doesn't mean your hands are tough. Sure, they probably won't blister now, but they can still rip open if you don't keep your calluses under control. Sure you could also wear gloves, but you really shouldn't have to resort to that, expect for really high-rep workouts.

Get this thing. Use it weekly.
