Getting the knives sharp

It is important to have a sharp knife, especially when you are butchering chickens.  Odd as it seems, a sharp knife is safer than a dull one since a dull one requires pressure to cut.  That pressure can cause slippage, which can be disastrous.  We'll be butchering 47 chickens tomorrow and cutting up chicken requires a very sharp knife.  My knives need sharpening.

So I use a whetstone, some honing oil and a sharpening steel to do the job.  You can see that this particular whetstone has a coarse side and a fine side.  I have several Chicago Cutlery knives that we've found are up to the task of cutting up chickens tomorrow.  I lay it all out on a towel since the grit from the stone can make a mess and I don't want to ruin the carpet.  The towel serves another purpose - it keeps the stone from slipping.
Knives, whetstone, honing oil and a steel

First I put a drop of honing oil on the coarse side of the stone.  The oil acts as lubrication.
  
Putting a drop of oil on the whetstone.

With the non-dominant hand on the blade and the dominant hand on the handle, I hold the blade at a 20 degree angle and with moderate pressure, I push it forward covering the entire length of the blade from tip to base.  Repeat this process 10 times and then flip the knife open and do the same thing on the other side.

Now we flip the whetstone over to the fine side and repeat the same process as with the coarse side above.

In similar fashion as explained above, while holding the knife at a 20 degree angle, I push the knife forward with moderate pressure from tip to base.  I do this 10 times and then flip the knife over and do the same with the other side.

Finally, I finish the process using a sharpening steel.  Sharpening a knife using a whetstone grinds away tiny bits of the knife blade and it leaves the blade's edge rough and uneven.  The sharpening steel then smooths out the blade's edge.  I'll use the steel from time to time tomorrow in order to keep the blade sharp while butchering chickens as I notice that the blade is dulling.  It is important to keep the knives sharpened at all times.
Finishing up with a sharpening steel
Knife sharpening takes time and must be done time after time when cutting chickens since you're cutting through bone.  This takes its toll on your knife.  A sharp knife is a safe knife and hopefully will make our job easier tomorrow morning.
