Manual log splitter advice

I am looking at some manual log splitting tools.  I am older women and need something simple. My neighbor chops firewood for me, but sometimes they are too big for my stove. Every so often I need to split them smaller. I have seen ads for the ones in this link.  Any recommendations on any of these.  I am especially looking at the black ones that are tall and have circle at top to hold the wood.

Hi Jan;

This is my reply from your other post on the tips and tricks thread.
I  checked out the splitters you are looking at.
I noticed that 9" or less is the max diameter, length is limited as well. One had 15" max and the common firewood length is 16".

Are you looking at manual splitters because you have no electricity?
I always split my own wood until this past spring, when I broke my dominant right wrist.
Spitting wood by hand was not possible after that.
I purchased a Wen 6.5 ton electric spitter.
I modified it so it had a foot pedal switch instead of a push button.
I also modified it so I only needed to push a lever to retract the ram.
Those modifications are the cats meow!  It is fun and easy to use now unlike the way it was when it arrived.
The cost was apx. $300 after buying the foot switch.

A wood splitter isn't something you need year 'round. Can you rent one and talk neighbours/friends/family into spending an afternoon? Food and adult beverages have proven an effective bait.

I split my wood by hand. With some of the gnarly, knotty spruce I'm dealing with I plan to cut it into 12" cookies so it'll split into quarters with two swings of the maul. It'll burn just fine regardless.

We use the kindling cracker XL King and can highly recommend it.

I have had tendonitis in my right wrist so have had to use my left hand to hold the mallet.

So long as the logs aren't too knotty, they split really easily  - I am 5'1" and in my 60's!
