I used to do this once in a while when I was new to grooming.
I would pick up my clippers and forget to check the blade.
I would start to clip only to realize that I had the wrong blade on my clipper.
Oh, that feeling when your stomach drops to your feet as you look at the hole in the hair.
If only you could rewind the last five minutes of your life.
Just imagine...the dog you are clipping is supposed to get clipped with a #4F blade.
You pick up your clipper, you place it on the dogs back, taking your first swipe down the back.
You clip about an inch of the dogs back, just enough to realize, too late, that you have a #10 blade on your clipper.
You stand there and stare at that hole in the hair.
You stare at it, trying to will it away.
You stand there cussing at yourself.
I only needed this to happen a few times, to drill it into my head, to make sure that I always check the blade before I start to clip.
Yes, sorry to say that it took a few times messing up to teach me.
Slow learner I guess. :(
Thankfully I almost always was able to use thinning shears and or scissors to fix the hole by blending all around it.
All but that one Poodle mix.
Nothing helps fix a hole in the hair of a creme colored poodle mix that was supposed to get a #4F blade on the back...not the #15 blade.
Could it be any more embarrassing then to go up to an owner and try to explain that you started clipping their dog with the wrong blade?
That customer was very nice and understanding, but I was still embarrassed.
That was a long, long time ago.
It is very second nature for me to check the blade on my clipper before I start clipping.
I don't even really think about it anymore.
I haven't put a hole in a dogs coat in a long time.
Well.....until the other day.
I had a regular in.
He comes in every 8 weeks.
His Mom likes him very short.
He gets a #4F blade on the body, the head blend the ears, scissor the legs, and trim the tail.
So, I picked up my clipper and stared to clip.
The only problem was, I didn't just clip a small hole.
I clipped the top of the head and part way down the neck before I though; 'boy, this #4F is cutting nice and smooth."
At the exact time this thought is going thought my head, my little voice is screaming at me; 'you're using the wrong blade stupid!'
Too late, I looked at the blade.
Not like it was a teeny, tiny number you can't read in the corner!
Of course, after all of these years, I can tell what number blade it is just by looking at the teeth, even if it didn't have a gigantic number printed on it.
Thankfully, a #5F blade is not that much different from a #4F blade.
I was able to continue with the #4F blade without having to do very much blending.
I couldn't believe that I did that!
I always check the blade.
What makes it worse, is that I clipped more than just a small spot before I registered what I done.
Every once and a while, something will happen to shake you up, and make you remember that you must always stay alert to what you are doing while grooming.
When you get too comfortable, you can make mistakes.
Thankfully, this one was a minor mistake.
Happy Grooming, MFF
