If you’re not a D_I_Y type of guy there’s probably nothing to do but to become frugal and save your money till you have enough to purchase ready made tying tools.
However, some people with the D_I_Y spirit have come up with ways to make their own tying tools. Maybe not as convenient to use as refined manufactured tools. However, if you have more time than money. Here are a few ideas.
The basic materials needed are : heavy electricians pliers , rubber bands, #14 ( 2mm) wire, some lighter wire , two bolts and acorn nuts, and a couple of old ball point pens.
Here’s the Japanese web site where I found these ideas. Click on the web page link to see more details.
Starting with a substitute for a vise
Heavy pliers and rubber band vise – if you already own pliers like these maybe worth a try. If you don’t own pliers like these , buying a pair would probably cost as much as a low end vise.

Thread /bobbin holder– made from #14 wire , a tube from a ball point pen. Two bolts and acorn nuts and some lighter #30 wire.

Version 2, more details on the web page above.

Hackle pliers – this was his idea, one of those holdable binder paper clips. To which he attaches a bit of string to make a finger loop, which is shown better on a separate web site.

But I think there are better alternatives, ( Mini hook test clips from Radio Shack) These are actually sold as hackle pliers with a nice wire loop to hook your finger in. However, if you order one the postage would probably be more than the price of the tool. Or you can buy the mini hooks at your local electronics store and make the wire loop from left over wire used to make the bobbin holder. Click the links below to see versions sold as fly tying tools.

Funny, but the second link above says the pliers with the wire finger loop, shown on the first link, is junk. Still the finger loop would be easy enough to make. The folks at warmwatrflytyer do speak highly of the feather-craft product, scroll down about halfway to see the Unique Hackle Pliers entry, I couldn't link to it directly.

And there are multiple uses for the mini hooks ; with some added wood work you can make a nice display stand to hold the kebari while you take a photo of your creation to post them to the forum.

More display stands shown on the below web page.

Half hitch tool – an opportunity to use the body of the ball point pen. I have to admit that though I own a half hitch tool and have one built into the end of my wipe finisher I never use it and just tie half hitches by hand.

Whip finisher. Use the rest of the wire used to make the bobbin holder and the rest of your ballpoint pen tube.

More details on the web page above.

There are other tools listed on the web page; hair stacker and a dubbing tool. Just click on the other links on the page. I didn’t link them here because these are the essential tools for tying the basic tenkara kebari.
fwiw - maybe useful - maybe not for those on a tight budget. Even if the tools aren't of interest the kebari display stands are pretty cool.
