I was literally getting ready to sharpen my spear with a file when this video appeared at the top of my feed. Rob Allen saves the day! Big thanks for the relevant video!
Good advice 😎🤙🏽🌺 I thought building a simple jig with the desired sharpening angle that also turns 120 degrees to switch to next phase. But I spend too much time in the water... anybody knows if such a jig exists already?
I have no drama with a good sharp file. I have restored some very damaged tips from mates shooting rocks and still manage to get facet angles and lengths exact. A linisher/belt sander and jig would be easier though.
Good day Rob. Any chance you could make a batch of spears for pneumatic guns? I can send over a template for the threaded tail portion. Loving the videos, can't wait to come back to KZN for some soul fishing.
No problem, just need to know the thread. Some I have seen are 6mm metric. We can thread both ends. One problem, being plated, your line slide might scratch up the plating. What diameter are you looking for? We do 6,3mm, 6,6mm, 7mm, 7,5mm and 8mm only.
@@RobAllenSpearfishing Fantastic stuff! I use 7mm, 7.5mm and even 8mm when there's halibut about. Line slides are currently holding up well in plastic and delrin so no worries there. Will figure out a decent way to ship them Northwards (I relocated to Norway many moons ago) and get back to you. Just by chance, I'm currently starting up my own maritime business here - do you need a good dealership for Norway or Scandinavia? I'll do some mad fun promos for your kit!
A bench grinder is difficult because as you see, best to grind away from you but also onto a flat surface. The outer edge of a bench grinder has a radius. If you could mount the bench grinder on its side and use the side of the stone it could work. It is best when you can visibly see the 2 edges against the stone at the same time to keep them uniform.
It would be nice if you can redo this one day for people with zero tools. I mean I live in a condo. I do have a file I suppose that’s all I can do, but certainly can’t get it very refined unless I’m just doing something wrong
@@RobAllenSpearfishing thanks. I don’t have any sort of clamp and often find that is the most difficult part. Could a hand vice grip work? I don’t have one but that’s something I could get
As long as you do not get it red hot it will be fine. The straw colour is ok. Grind slowly with time between grinds to cool. I have only once tried to re heat treat the tip, did not seem to make a difference but as a one off was hard to tell. In retrospect, the transitional zone between the heated tip and the rest of the spear might be an issue, never tested though.
Wash well and dry with fresh water. Our spears are a trade off against stainless. Stainless don't rust but are no where near as stiff, much more likely to bend and, much higher cost.
Hey Rob I bough one of your spearfishing knifes a few weeks ago and love the design and slim profile but buy the time I got home from using it fir the first time today the knife was covered in rust spots I say I was using it but it was completely blunt the bevels where ground completely uneven and the tip was as dull as a spoon I think there is a problem with quality control where these where made I for one would be ashamed if my name was attached to this knife especially whe its primary function after dispatching fish is safety
I can understand and deal with the rust spots you want to make a blade that retains its edge and is strong but sending them out completely blunt with a rounded tip is disgraceful

Thanks , nice tips
i was going through your channel two days ago looking for a video like this, thanks rob allen for the information
Thanks Rob, very informative and to the point (ha ha) as usual. Hope the situation is getting better in Durban! Cheers 💯🙌🏽👍🏽😎
All good now, thanks for asking 👍
Spot on Rob. Great advice as usual thankyou :)
The more I watch the more I see how clever Rob Allen is.
Thank you for the kind comments.
Thanks Rob, great advice

Sir what's the differences between the tuna and the carbo ?
Question, is the formation of this tip when sharpening better than the tips that have a conical shape ?
For cutting flesh and bone, definitely a yes.

@@endosapien
Thanks for that. We do have a distributor in Norway, not sure if he does Scandinavia as well.
Mind to share us with the grit of the sand disc you used in the video, please?
sorry for the late response. 60 to 80 grit will be fine.
@@RobAllenSpearfishing thanks for your reply
Good stuff but what I use
Is a file
We use to sharpen machetes
Is a bench grinder ok, or do you need to grind away from you?
A bench grinder is difficult because as you see, best to grind away from you but also onto a flat surface. The outer edge of a bench grinder has a radius. If you could mount the bench grinder on its side and use the side of the stone it could work. It is best when you can visibly see the 2 edges against the stone at the same time to keep them uniform.
What sanding disc did you use in this video?
No sure, I think 80 grit. The finer the grit the slower it will take off material, but easier to control.

Doing it with a file hand held would be very difficult, do you have a way to clamp the spear?
@@RobAllenSpearfishing thanks. I don’t have any sort of clamp and often find that is the most difficult part. Could a hand vice grip work? I don’t have one but that’s something I could get
@@bluedoggum8373 Give me a few days to look for possible openings.
Lot of youngsters r getting into spearfishing but,but it's difficult to find spearguns in India
Online store would be a good idea in southern India
Hi Floyd, we are open to anyone wanting to invest in a distribution in any country where there is not a distributor already, like India.
Wich angle have to be the spear to sharp it ?
Sorry, just seen this, about 30 deg.
Thanks alot!!
From South Africa?
Yes
What to do if the material is annealed
As long as you do not get it red hot it will be fine. The straw colour is ok. Grind slowly with time between grinds to cool. I have only once tried to re heat treat the tip, did not seem to make a difference but as a one off was hard to tell. In retrospect, the transitional zone between the heated tip and the rest of the spear might be an issue, never tested though.
What is the ideal degree
About 30 deg is good.
How to prevent your spears from rusting...???
Wash well and dry with fresh water. Our spears are a trade off against stainless. Stainless don't rust but are no where near as stiff, much more likely to bend and, much higher cost.

@@leecollins8692 Hi Lee, I agree this should not happen, I will check our stock. Where are you in the world?
@@RobAllenSpearfishing I am in the UK
how i wish rob allen had rods with rest pegs in america
It can be done but the heat from the welding will make the spear soft at that point and very easy to bend when you shoot a fish.
@@RobAllenSpearfishing at least one lug rest, to facilitate loading, and not having to dive with the loading tool
@@EuroYepes As mentioned, can be done but we would not recommend it because the spear will get bent with very little force.
Bro that my name
osha ? nope no osha here.
I would hope that OSHA is not wasting their time with what people is South Africa are doing.
