[A cane that is not handle heavy is awkward to actually carry, though one can get used to anything. But why have to?
The taper is both elegant and useful!
The 'thin' end (think piercing) has the necessary added weight of a ferrule and bolt.
That seems to be all the counter-balance necessary, if the proportions of the rest is correct.
Any old stump or sapling will not have the necessary qualities necessary for a quality martial cane.
I can go through multi-thousands of saplings and branches before finding a suitable stick for a shillelagh.]
I too like a bit of taper in my cane/stick. It makes for a faster handling stick, and I always use my stick in a tow hand hold like a pugil stick. To me, bottom of the taper is like the tip of the spear, or the bayonet. I will parry, block, and thrust with the tip. I like a taper stick with the heavier end of the balance up toward the handle so I can b e a bot quicker to target the face, throat, and stomach area. Since I use pugil stick methods, I hold the stick like a bayonet equipped rifle or a spear. All my sticks have blackened brass end caps under the rubber cane end, and If I have an inkling of trouble coming, I do remove the rubber end. Only takes a second to pull it off.
I can't forsee any situation that I would be using my stick like a club, so weight is not an issue. Any strikes I make with a stick, will be a two handed thrusting blow with an end. If not the tip of the spear, then a "butt stroke" with the root knob handle under the chin into the throat or into the face. Once you impair the attackers vision or breathing, you're on the way to getting out of Dodge.
The big thing is, if you do really mess somebody up, the more 'innocent' your stick looks, the better. If it looks like a African war club, not good. If it has metal added to load it, not good. If some idiot low life sues you hoping to get some payback because you blinded him in one eye, or put him in the hospital, whatever you used will be held up in front of a jury. If they hold up one of my lighter sticks with a nice taper, and it's not some thick club of a stick, it's going to be very hard to make a case. If it's one of those all metal adjustable canes like a drug store cane, even better. Last year, I had another operation on my right foot for some old service damage, and the V.A. hospital gave me a nice black aluminum cane that was adjustable. Had a very nice foam cushion grip.
It was too light for a club, and as Owen said, would bend when hit on a tree. But I don't plan on being mugged by a tree, and the tubular aluminum makes for a very strong thrusting spear. I put a much narrower diameter rubber end on it, and did some practice, and I found out that the weird curve of the tube coming up to the handle made a really, really good tool for blows to the face and neck, like a big brass knuckle. Once I realized how to use the weird shape, it worked very good as a close in grapple tool.
Tools are tools. Once you learn to maximize the use of the particular tool, you don't need cheep and illegal tricks like loading a cane. If push comes to shove, you will have to hurt someone. The law is going to be involved, so look as innocent as possible. Even a drug store aluminum cane can be used it you practice with it and find what it will do vs can't do. Every tool has it's strong points, just as every tool has it's weak points. A 5 shot Chief's special won't give you the firepower of a 1911, but it has protected generations of people with it's 5 rounds of .38 special. When Lou Ciamillo was at Maryland Gun Works, he showed me what a J frame was capable of, when I was going to trade mine in. He convinced me to go home and practice with it, and I did. To this day, I still have that little .38, and it has been a lesson to me. I'll never forget what he told me. "If the person shooting the gun doesn't do a good job, it's not the tool's fault. The man holding the weapon is responsible for the use of it."
I think that pretty much goes for any tool. If you have blinders on, then it's not the tools fault that you can't see the strong points of how to utilize it.
